I posted this question yesterday, but there is another part of the problem I don't understand A 0.76 kg fireworks rocket moving at a speed of 32 m/s breaks into two pieces as the result...

Postulates of the Kinetic-Molecular Theory of Gases: 1. Gas particles are extremely small and have relatively large distances between them. 2. Gas particles act independently of...

In elastic head-on collisions, the relative speed of the two objects before the collision is equal to the negative of their relative speed after the collision, no matter what their masses are. Prove...

A 59 kg pole-vaulter is trying to jump over a 5.06 m bar. By pulling and projecting themselves off the pole, the athlete can add 15% to their maximum kinetic energy and vault higher. Assume that the...

An asteroid with a mass of 5.0 x 105 kg collides with the Earth and slides horizontally along the ground without bouncing (not actually possible but just pretend). The velocity of the asteroid before...

A 45 kg student runs with a speed of 2.0 m/s off a horizontal ledge that is 5.0 above a swimming pool. Calculate the vertical speed of the student when she hits the water. ... Energy...

In an attempt for a physics teacher to explain the conservation of energy to a student, the teacher goes down a 6.0 m high sliding board. At the bottom, he only travels 7.0 m/s. If the mass of the...

A small ball has a mass of 5.0 x 10-8 kg and a charge of 0.0 x 10-5 C. It enters a box with an initial speed of 1.2 x 104 m/s. The point where the charge leaves the box is at a voltage 350 kV higher...

Two charges q1 = −3.20 nC and q2 = +8.15 nC are at a distance of 1.28 µm from each other. q1 is fixed at its location while q2 is released from rest. (a) What is the kinetic energy of...

A small car of mass 500kg is travelling at 120km/h when it hits stationary truck (of 1.5 tonne mass) head on. The small car rebounds and travels in the opposite direction at 40km/h. The collision...
