3) When the rope is at an angle of a= 30° the 1-1b sphere A has a speed vo= 4 ft/s. The coefficient of restitution between A and the 2-1b wedge B is 0.7 and the length of the rope /= 2.6 ft. The spring constant has a value of 2 lb/in and 0= 20°. Determine: a) Velocities of A and B immediately after impact b) Maximum deflection of the spring assuming A doesn't strike B again. a B

The 1900-kg car has a velocity of 21 km/h up the 10-percent grade when the driver applies more power for 13 s to bring the car up to a speed of 64 km/h. Calculate the time average F of the total force tangent to the road exerted on the tires during the 13 s. Treat the car as a particle and neglect air resistance. 10 100 Answer: F = i kN
