A car travels on a straight road as follows: it moves northward for 150 km in 2.00 h, then makes a right‑angle turn and moves eastward for 120 km in 1.50 h. During the eastward leg a steady wind blows from the west at 20 km h⁻¹. The engine exerts a constant force of 5.0 × 10³ N in the direction of the car’s motion during the eastward leg.

Question Parts

( a )
Calculate the average speed of the car for the whole journey.
( b )
Determine the magnitude and direction (bearing measured clockwise from north) of the average velocity vector for the whole journey.
( c )
During the eastward leg, find the resultant velocity of the car relative to the ground, taking the wind into account. State its magnitude and direction (angle measured north of east).
( d )
Calculate the work done by the engine during the eastward leg of the journey.
