Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

**Physics Problem: Inelastic Collision and Energy Conservation**

A 14.2 g bullet is shot vertically into a 2.64 kg block. When the bullet penetrates the block, it comes to rest in a time interval of 1.12 ms. The block lifts upward 9.30 mm vertically with the bullet embedded. Ignore air resistance and ignore the force of gravity during the 1.12 ms embedding time.

Find:
(A) the initial kinetic energy of the bullet before the collision and
(B) find the percentage of this energy lost as heat during the collision.
After your calculations,
(C) show that it was a good approximation to ignore the force of gravity during the 1.12 ms it took the bullet to come to rest in the block.

**Diagram Explanation:**

The diagram shows a bullet moving vertically upward into a block. The block is represented as a large rectangular shape, with the bullet depicted below it in its path of motion. An arrow pointing upward indicates the direction of the bullet's velocity as it moves towards the block. The motion is taking place within a cylindrical boundary represented by shaded lines.

Q22. As shown in the image below, the force acting on the 5-kg crate is a function of time. The coefficient of kinetic friction between the crate and the surface is uk = 0.15. Determine the magnitude of the horizontal impulse (in N-s) done by all external forces to the crate during the period from t = 0 to t= 2.3 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.

A heavy goods vehicle of total mass 4.8 tonnes descends a hill with a gradient of 8 degrees from the horizontal. During this motion, the vehicle experiences a rolling resistance to its motion of 880 N. Whilst travelling at a velocity of 72 km/h, its brakes are applied, and the truck is brought uniformly to rest in a distance of 140 m. During this period of constant deceleration, it may be assumed that the rolling resistance remains constant at 880N, this being in addition to the retarding force applied by the brakes. Calculate for the vehicle whilst it is slowing down: a) The vertical height through which it descends. b) Its decrease in potential energy. c) Its initial velocity in m/s. Its decrease in kinetic energy.
During an Olympic 100-m sprint race, Usain Bolt, the world record holder in that race, quickly accelerates to his top speed of 12.4 m/s. Analysis of his technique has shown that each of his feet make contact with the ground for 0.0800 s, exerting a force of magnitude 2.80 x 10° N during this contact. This allows the 94.0 kg Bolt to leap forward and remain airborne for 0.120 s until the next foot touches the ground. (Ignore air resistance.) (a) What are the magnitudes of the horizontal and vertical components of the force (in N) Bolt's feet exert on the ground?
