Question

Example 4 : A motorboat starts from rest
and moves with uniform acceleration. If it
attains the velocity of 15 m/s in 5 s,
calculate the acceleration and the distance
travelled in that time.​

Answer 1

Answer:

a = v-u/t

using this formula,

a = 15-0/5

= 3m/s

S= u+ 1/2at2

= 0 + 1/2*3*5*5

= 75/2

= 37.5 m
