A car accelerates at 3 m/s*2. Assuming the car starts from rest, how much time does it need to
accelerate to a speed of 12 m/s?
3 sec
2 sec
4 sec
12 sec
None of the other answers
Acceleration,a = 3 m/s²
Initial velocity,u = 0 m/s
Final velocity,v = 12 m/s
To be calculated:-Calculate the time take by a car.
Solution:-According to the first equation of motion:
v = u + at
★ Substituting the values in the above formula,we get:
⇒ 12 = 0 + 3 × t
⇒ 12 = 3t
⇒ 3t = 12
⇒ t = 12/3
⇒ t = 4 sec
We are given with some parameters used in Kinematics for determining the motion of an object.
Accleration = 3 m/s²Started from rest (Initial vel.) = 0 m/sFinal velocity = 12 m/sWe have to find the time taken by the car to attain the final velocity with the given accleration. By using 1st equation of motion which says:
v = u + atFinal velocity = Initial velocity + Accl. × Time taken
Plugging the values,
➝ 12 = 0 + 3(t)
➝ 3t = 12
➝ t = 4 s
So, the correct answer is Option C. And we are done...

When a teacher mixed zinc (Zn) with hydrogen chloride (HCl), one or more new substances formed. Hence, option (d) is correct.
What is chemical reaction?A chemical reaction is a procedure that causes one group of chemical components to change chemically into another.
Chemical reactions, which can frequently be described by a chemical equation, traditionally include changes that only affect the locations of electrons in the formation and dissolution of chemical bonds between atoms, with no change to the nuclei (no change to the elements present).
The study of chemical processes involving unstable and radioactive elements, where both electronic and nuclear changes may take place, is known as nuclear chemistry.
When the teacher mixed zinc (Zn) with hydrogen chloride (HCl), chemical reaction happens and more than one new substances formed.

Answer:
The final velocity of the ball is 39.2 m/s.
Explanation:
Given that,
A ball is dropped from rest from a high window of a tall building.
Time = 4 sec
We need to calculate the final velocity of the ball
Using equation if motion

Where, v = final velocity
u = initial velocity
g = acceleration due to gravity
t = time
Put the value into the formula
[tex]v=0+9.8\times4[/tex]

Refer to the position time graph provided to answer questions #1 thru 5.
1. What is the instantaneous velocity of the object at 5 s?
2. What is the distance the object moves from 0 to 9 seconds?
3. What displacement did the object have between 2 s and 9 s?
4. What was the object's average velocity over the first 5 seconds?
5. How many times does the object change direction of travel? (time zero
does not count and standing still does not count as a direction change)
Answer:
Explanation:
1). To calculate the instantaneous velocity of the object, we will calculate the slope of the line CD.
Since line CD is a straight line, therefore, slope = 0
Hence instantaneous velocity = 0
2). Distance of the object when it moves from 0 to 9 seconds
= Distance traveled from (A to B + B to C + C to D + D to E)
= 3 + (3 + 0.5) + 0 + 0.5
= 7 m
3). Displacement = Distance between initial and the final positions of the object
= 3 - 0
= 3 m
4). Average velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]
= [tex]\frac{0.5}{5}[/tex]
= 0.1 m per sec
5). Direction changes have been seen at t = 2 sec and t = 4 sec.
Hence object changed its direction of travel 2 times.
What is the momentum of A 200 kg shark swimming at 15 m/s
Answer:
3000 kg meter per sec
Explanation:
Momentum of an object refers the motion of an object. Momentum depends upon mass and velocity both.
Formula to calculate the momentum of any object is,
Momentum = Mass × Velocity
By substituting values of mass and velocity of the shark from the question,
Momentum of shark = 200 × 15
= 3000 kg meter per second
Therefore, shark weighing 200 kg has the momentum as 3000 kg meter per seconds.

Why is it important to describe motion in universal terms?
Answer:
Motion requires force to cause that change. The time you take to travel the distance depends upon speed; the distance travelled is measured as the length of a line between the start and end of a motion. It is an important aspect in physics. In our lives motion is important and impacts so many things that we do.
Explanation:
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.
The motion of an object occurs when there is change in the position of the object with time and the object moves in the direction of the applied force. This motion is influenced by the net force acting on the object.
For example:
The dimension of speed of object in motion is measured with two fundamental quantities (length and time);
speed = LT⁻¹
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

A cannon is fired horizontally from the edge of a 100 meter tall cliff. The muzzle velocity of the cannon is 180 m/s . How far from the base of the cliff does the hall land?
A-.55m
B-813.16m
C-3673.47
D-700m
Answer:
B - 813.16 m
Explanation:
First, find the time it takes to land. Given in the y direction:
Δy = 100 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
100 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 4.52 s
Now find the distance traveled in that time. Given in the x direction:
v₀ = 180 m/s
a = 0 m/s²
t = 4.52 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (180 m/s) (4.52 s) + ½ (0 m/s²) (4.52 s)²
Δx = 813.16 m
