(14 The wheelbase of a car is 3-3 m, and the centre of mass is 1 2 m in front of the rear axle and 0-75 m above the ground-level. The coefficient of friction between the wheels and the road is 0-45. Find the maximum acceleration which the car can be given on a level road if it has a rear-wheel drive. Find its maximum deceleration if the braking force on all the wheels is the same and no wheel slip occurs. ​

Sagot :

if the static coefficient of friction mew between the tires and the ground is 0.55, then the maximum acceleration of the car will be 0.55g with assumption that there is enough engine power. 0.55g is about 5.4 m/s/s.
