First, let's convert the final velocity from km/h to m/s:

Next, we'll calculate the acceleration using the formula

Now, we can calculate the force using
F=ma, where the mass m = 1150 kg.

=
3450N
The next step is to calculate the work done using


Now, we'll use the formula for power:

,where
t=7.4s

Rounding to two significant figures, the average power delivered by the engine is approximately

So, the average power delivered by the engine is around 39 kW.
