Question

An object starting from rest on a river accelerates in a straight line at a constant rate of 2.0 m/s2 for 10 s. How far does the object travel during this time.​

Answer 1

Answer:

We know the equation of motion.

Distance, s = ut + (1/2)at2 —————-(i)

Substituting the given and known values in the equation (i) we get,

s= 0 (8) + 1/2 (3) (8)2

= 1/2 (3) (64)

= 3(32)

= 96

Therefore, the distance travel by motorboat = 96 m
