A 15,800 kg truck is moving at 12 m/s when it starts down a 50 incline...
1. A 67-kg base runner begins his slide into second base when he is moving at a speed of 4.5 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. (a) How much mechanical energy is lost due to friction acting on the runner? (b) How far does he slide? 2. A 0.32-kg stone is held 1.4 m above the top edge of a...
A 1050 kg sports car is moving westbound at 15.0 m/s on a level road when it collides with a 6320 kg truck driving east on the same road at 12.0 m/s . The two vehicles remain locked together after the collision. (need help with D and E) A) What is the velocity (magnitude) of the two vehicles just after the collision? 8.15 m/s C) At what speed should the truck have been moving so that it and car are...
A 1050-kg sports car is moving westbound at 15.0 m/s on a level road when it collides with a 6320-kg truck driving east on the same road at 10.0 m/s. The two vehicles remain locked together after the collision. (a) What is the velocity (magnitude and direction) of the two vehicles just after the collision? (b) At what speed should the truck have been moving so that it and the car are both stopped in the collision? (c) Find the...
