How does the mass of a wheelchair influence the force needed to move it?

Answers

Answer:

When mass is greater, the force needed must be greater keeping the acceleration of the wheel chair constant

Explanation:

[tex]force = mass \times acceleration \\ f \: \alpha \: m[/tex]

force is directly proportional to the mass

The force needs greater keeping of the wheel chair

A car is moving at 80km/h accelerates to pass a truck. Five seconds later the car is moving at 100km/h. What is the Acceleration of the car? Please show the equation, Ty.

Answers

Answer/Explanation:

Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:

acceleration = v - v0 / t

acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s

acceleration = 1.67 x 10^-3 m / s^2

a = V2-V1 ÷ Δt
a = 27.78 m/s - 22.2 m/s ÷ 5 seconds
a = 1.116 m/s ²

*you needed to convert the km/h to m/s for proper evaluation, which is what i did*

Answer:

A) y = 1.3x + 10

Explanation:

2 Points on the graph by using x and y values:

(0, 10) and (10, 23)

Slope:

m= (y2-y1)/(x2-x1)

m= (23 - 10)/(10 - 0)

m= 13/10

m = 1.3

Slope-intercept:

y - y1 = m(x - x1)

y - 10 = 1.3(x - 0)

y - 10 = 1.3x

y = 1.3x + 10
