(a)[1]
Define what power is.
(b(i))[1]
For the car’s journey from A to B, state the change in kinetic energy.
(b(ii))[1]
For the car’s journey from A to B, calculate the work done against the total resistive force.
(c(i))[2]
In (b), the car’s movement from A to B increases its gravitational potential energy by $4.8 \times 10^{4}\,\text{J}$. Calculate the vertical increase in height $h$ of the car for its travel from A to B.
(c(ii))[1]
Calculate the angle $\theta$.
(d)[2]
The car’s engine in (b) delivers an output power of $1.7 \times 10^{4}\,\text{W}$ to drive the car up the slope. Calculate the time taken for the car to move from A to B.
