- A 15 kg bullet is fired into 3 m long pendulum and that into the pendulum if the pendulum has the mass of 2.8 kg and it rise a vertical distance of 15 cm what was the initial velocity of the bullet at the moment it hit the pendulumWater falls without splashing at a rate of 0.250 L/s from a height of 2.60 m into abucket of mass 0.750 kg on a scale. If the bucket is originally empty, what does thescale read in newtons 3.00 s after water starts to accumulate in it?A train engine weighs 4 times that of a railroad car. The engine collides into the car (initially at rest) and they both stick together. If the speed of the train engine before the collision was 6 km/hr, find the speed of the system just after the collision. Show you work.
