A truck of mass 1000 kg accelerates uniformly from rest to a velocity of `15ms^(-1)` in 5 seconds. Calculate (i) its acceleration, (i) its gain in K.E., (iii) average power of the engine during this period, neglect friction.

Explanation

To solve the problem step by step, we will calculate the acceleration, gain in kinetic energy, and average power of the truck.

### Step 1: Calculate Acceleration
The formula for acceleration \( a \) is given by:

\[ a = \frac{v - u}{t} \]
