Question

A pupil pushes a wheelbarrow carrying 30kg sand it accelerates from rest to 2m/s in the distance of 1m. If the friction is on the wheelbarrow is 0.5n find accelaration

Answer 1

average velocity ... (0 + 2) / 2 = 1 m/s

takes one second to travel 1 m and accelerate to 2 m/s

Answer 2

V^2 = Vo + 2a*d.
2^2 = 0 + 2a*1,
a = 2m/s^2.
