A wagon with a mass of 35 kg is pulled so that it accelerates from 0 m/s to 30 m/s in 15 seconds.
Remember to show all work!
a. What is the acceleration of the wagon?

b. What is the force required to get this acceleration?

Plz help me

Explanation:

a = v-u/t

a is the acceleration of the body

v is the final velocity

u is the initial velocity

t is the time

Given

v = 30m/s

u = 0m/s

t = 15secs

Substitute

a = 30-0/15

a = 30/15

a = 2m/s²

Hence the acceleration of the wagon is 2m/s²

b) Force = mass * acceleration

Given

Mas of the wagon = 35kg

acceleration a = 2m/s²

F = 35*2

F = 70N

Hence the force required to get this acceleration is 70N

Power

Explanation:

If the force is constant, then you get the instantanious power is the force dotted to the instantaneous velocity (constant force means velocity .
