Pool ball moving is with velocity of 1.5 m/s. It hits a second pool ball of equal mass, initially at rest. After the collision the first ball moves off at 370 angle from its original direction with a speed of 1 m/s. Find the velocity (magnitude and direction) of the second ball after the collision.

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

5g of ammonium nitrate was dissolved in 60g of water in an insulated container. the temperature at the start of the reaction was 23.0°c and at the end it was 19.0°c. calculate the energy absorbed by the reaction.
