A moving object is moving with a speed of 20m/s on the line y=√3x +1. How many meters does it move in the x direction in 3 seconds?
how can i solve it?
2077 m distance it move in the x direction in 3 seconds
speed=distance/time
distance=speed × time
distance= 20×3
√3x +1=60
x=119
put x's value in equation
distance= 2077 m
Distance, which is independent of direction, is the length between two points or things. Distance solely considers the overall magnitude and disregards the start and finish places because it is a scalar attribute. Distance can only have a positive or zero value because it is a scalar attribute; it cannot be negative.
The meter (m) is the most widely used unit of measurement for distance, however kilometers (km) can also be used to describe longer distances and centimeters (cm) or millimeters can be used to express shorter distances (mm). The distance traveled is frequently represented by the letter D when computing distance.

The diagram shows object N placed one on top of object M. M has a mass of 4 kg and N has a mass of 2 kg. Assume that all the contact surfaces are frictionless, what is the acceleration of N when M is
pulled by a force of 20 N?
A. 0 m/s²
B. 4 m/s²
C. 3.3 m/s²
D. 10 m/s²
If N placed one of these on top of item M, the acceleration when M is dragged by a force od 20 N is 10 m/s. N weighs 2 kg, but M is 4 kg in weight.
The correct answer is D
What happens during acceleration?Acceleration is the rate at which the direction and speed of a moving object change over time. Anything is said to be accelerated when it goes straighter and faster or slower. Therefore, even though the speed is constant, travel on a circle increases due to the constant change in direction.
Is a gradual incline good?Slow acceleration can be dangerous as well as unpleasant, especially when entering a busy state road when you must accelerate rapidly to avoid being rear-ended. When you are moving slowly up a slope while driving, acceleration can sometimes be a hassle.

During a thunderstorm, why do you see the lightning before you hear the thunder?
Answer:
light travel faster than sound
Explanation:
because light, travels at about 300,000,000 meters per second, travels much faster than sound, which travels at 340 meters per second
You do 13 J of work as you lift a 35-N pail of water. Through what height did you lift the pail?
Height to which the lift of the pail is taken is 0.37m.
Height is the vertical distance of an object from the surface of the Earth.
Work done = 13 J
Weight of the pail of the water = 35-N
Gravity is defined as the force that attracts a body to the Earth or any other physical body that has mass.
The acceleration due to gravity is denoted by 'g' which has the value of 9.81 [tex]m/s^{2}[/tex].Work done by gravity = mghW = mgh
mg = 13 J
W = 35 N
h = [tex]\frac{W}{mg}[/tex]
h = [tex]\frac{13}{35}[/tex]
h = 0.37 m
The height to which the lift of pail will be raised will be 0.37m.
