Question

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:

sorry bro

Explanation:

please mark as brainiest

Answer 2

Solution:-

Initial velocity=0

Final velocity=15m/s

Time =5seconds

So,

Acceleration = v-u/t

                      = 15-0/5

Acceleration=3m/s^2

Now,

we have to find Distance travelled,we will find it by using following equation:-

=  > s = ut +1/2 at²

=  > s = 37.5

Hence,

Distance travelled=37.5m
