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.

Q17. As shown in the image below, the 0.7-kg ball strikes the rough ground and rebounds. The directions of its velocities before and after the strike are shown. If the speeds are v₁ = 27 m/s and v₂ = 12 m/s, determine the magnitude of the impulse (in N.s) the ground exerts on the ball. Assume that the ball does not slip when it strikes the ground, and neglect the size of the ball and the impulse produced by the weight of the ball. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. V₁ Your Answer: 45° Answer 30° 02

Pr4. Two bodies are launched at the same time from two points A and B located at the same height. The distance between points A and B is d. One of the bodies starts from point A upwards with speed v1, while the other starts from point B towards point A with initial speed v2. What will be the minimal distance between the bodies during their motion? (The gravitational acceleration is g, neglect the air drag. The bodies do not reach the ground before the moment of the minimal distance.)
The 750-mm-long spring is compressed by the plate P, which can slide freely on the 600- mm-long vertical bars. The 55.6-kg block is given a velocity of v = 5 m/s when it is x = 2 m above the plate. Determine how far the plate travels down when the block stops momentarily after hitting it. Neglect the mass of the plate. v = 5 m/s P k = 25 kN/m- A h = 2m 600 mm
