A manufacturer is carrying out a vehicle performance analysis and subjects to a road test. The vehicle is driven along a horizontal road at velocity V. The vehicle weighs 1.79tons and for each wheel the radius is 0.31m and the MMofI is 5.53kgm2. The coefficient of friction between the wheels and the road surface is 0.43. Given g=9.81m/s2 and the length between the center of rear and front wheel is 3.9m. The height of center of gravity is 0.95m while its horizontal distance to the center of rear wheel is 1.72m. If only the front wheels are locked and there is no rear wheel braking, calculate the deceleration (m/s) of the vehicle. Submit your answer as a positive value.

2) After playing a game of pinball, you decide to do some calculations on the launching mechanism. The pinball and the plunger have a mass of 0.30 kg and 0.50 kg respectively. The spring coefficient in the pinball machine is 300 N/m. The original length of the spring is 100 mm and the compressed length is 35 mm. If the coefficient of friction between the ball and the surface is 0.15, calculate the velocity of the ball right before it loses contact with the plunger (in m/s). Note that the plunger is never in contact with the ground and assume the ball slides without rolling. [Ans. to check: 1.23 m/s] HO www
