Question 1 Report
A motorcycle starting from rest is uniformly accelerated such that its velocity in 10s is 72kmhr\(^{-1}\). What is its acceleration?
Answer Details
The formula for acceleration is given by: acceleration = change in velocity / change in time.
In this case, the change in velocity is 72 km/hr and the change in time is 10s. To use the formula, we first need to convert the velocity from km/hr to m/s.
72 km/hr = 72 x 1000/3600 m/s = 20 m/s
So, acceleration = 20 m/s / 10s = 2 m/s\(^2\)
Therefore, the acceleration of the motorcycle is 2 m/s\(^2\).
