Question 11 of 13
11. Question
The Figure below shows a car travelling at 30 m/s on a level road. At this speed the car has to overcome a total force of 600 N opposing the car.
(i) Calculate the distance travelled by the car in 10 s
(ii) State the value of the driving force produced by the engine for a steady speed of 30 m/s
(iii) While on the level road and travelling at 30 m/s, the driving force becomes zero. The mass of the car is 800 kg. Calculate the deceleration of the car.
-
Distance = m
Force = N
Deceleration = m/s square
