Question

What is the force needed to accelerate a wagon with a mass of 10 kg at a rate

Answer 1

Any amount of force will do that given time.

The time to accelerate a 10kg object to 2m/s from rest using force F is:

t = mv/F = 20/F

Is there a typo?

Was the 2m/s written, a speed, supposed to be 2m/s 2
2
, an acceleration?

If so, then it takes 20N to accelerate a 10kg object by 2m/s 2
2


… from F = ma.

Answer 2

Answer:

B

Explanation:

Remember:

F = m * a

 =  10 * 2  = 20 N
