Compute the following problem:
Q: A damaged 1200-kg car is being towed by a truck. Neglecting the friction, air drag, and rolling resistance determine the extra power required
(a) For constant velocity on a level road,
(b) For constant velocity of 50 km/h on a 30° (from horizontal) uphill road, and
(c) To accelerate on a level road from stop to 90 km/h in 12 s.
