Question

A vehicle starts to move foom rest and maintains an acceleration of 0.8 m/s2 in 10 second Calculate the final velocity and distance covert by the vehicle with in that time.

​

Answer 1

initial velocity, u = 0m/s (starts from rest)

final velocity, v = ?

time, t = 10 seconds

acceleration, a = 0.8m/s²

v - u = at

v - 0 = 0.8(10)

v - 0 = 8

v = 8m/s

speed = distance / time

distance = speed x time

distance = 8 x 10

distance = 80m
