Question

A motorboat starting from rest travels in a straight line on a lake. If the boat reahes a speed of 8.0m/s in 10s what is the boat's average acceleration?

Answer 1

The boat's average acceleration is  0.8 m/s².

What is acceleration?

Acceleration is defined as the rate change of velocity with time.

acceleration a = (Δv) / (Δt)

A motorboat starting from rest travels in a straight line on a lake. If the boat reaches a speed of 8.0m/s in 10s.

The final velocity v = 8 m/s and it starts from rest, then its initial velocity v = 0 m/s.

Time taken for the change in speed t = 10 s.

The acceleration is given by

a = (8 - 0)/ 10

a = 0.8 m/s²

Thus, the boat's average acceleration is 0.8 m/s².
