The bullet melting ice problem is a common example used to demonstrate the principles of thermodynamics. It involves a bullet being fired into a block of ice, and the resulting increase in temperature of the ice due to the conversion of kinetic energy into heat....
Homework Statement A 7-g bullet is fired into a 1.5-kg ballistic pendulum. The bullet emerges from the block with a speed of 200 m/s, and the block rises...
A pendulum consists of a wooden bob of massmand lengthl. A bullet of massm1is fired towards the pendulum with a speedv1. The bullet emerges out of the bob with a speed of(v1)/3and the bob just completes motion along a vertical circle, thenv1is ...
An 80 kg hunter, standing on frictionless ice, shoots a 42 g bullet horizontally at a speed of 660 m/s. What is the recoil speed of the hunter? Momentum: Momentum refer to the force quantity of motion that a moving object...
In summary, the bullet and chair impulse problem is a physics concept that involves analyzing the collision between a bullet and a chair. The problem often involves calculating the impulse, or change in momentum, of the bullet and the chair during the collision. This concept is important in ...
You: And how far had it penetrated into the chair? Det: A distance of 6.00 cm. You: Have you tested the gun you found in Mr. Smith's possession? Det: I have. You: What is the muzzle velocity of bullets fired from that gun? Det: The muzzle velocity is 450 m/s. You:...
(Choice of sign convention lay in user's choice , but then he has to stick to that convention throughout the problem.) So by Newton's third law , force which block exerts on bullet will be equal and opposite to force exerted by bullet on block. Since Δt is constant , so impulse ...
