Curling Sport Momentum and Collisions Physics Problem
Disappointed with a 4th place tin medal in bobsledding, Burl has decided to take up curling. One of the opposing team's stones is resting on the outer edge of the house as shown below. With which... more
How does an inelastic collision between the wall and a spring (connected to a device) affect the spring constant?
Calculating spring constant experientially with the methods of compression and collision (the question on the experiment is bolded in the description)
In an experiment, the spring constant (k) was calculated by gathering data on force and displacement from a compression (Part 1) and a collision (Part 2). In both parts, the spring constant (k) was... more
Momentum and Energy COnservation and Collisions
A block of mass M, at rest on a frictionless horizontal table, is attached to a rigid wall by an ideal spring with spring constant k. A bullet of mass m and speed v strikes the block and becomes... more
Bullet being shot into a block
A 0.0150kg bullet is shot into a 4.0kg block which is at rest on a frictionless horizontal surface. The bullet remains lodged in the block. The block moves into a spring and compresses it by 3.8cm.... more
Momentum and collisions
A 0.045-kg bullet traveling at a speed of 456 m/s is fired vertically into a sponge with a mass of 0.0060kg that is initially at rest. Assuming that the bullet is embedded in the sponge, how high... more
Small car colliding with large truck?
A small car collides with a large truck. Why do both vehicles experience the same magnitude of force? Wouldn't the large vehicle experience less force than the small one?
Ball flying towards me or me flying towards ball?
Suppose a ball is flying towards me at a speed of 10m/s and that, on impact, I feel "x" amount of pain. If, instead, it was me flying towards the ball at the same speed, with all other conditions... more
How do I describe and calculate the effect of an impacting object?
My lab studies the physiology of impact injury on biological tissues. I use a pneumatic cylinder to impart injury into a biological sample and then assess the molecular and physiological changes in... more
Can a bullet shot through a glass make a clean hole?
One can often see (hopefully only in the movies) that a bullet shot through a pane of window glass leaves a hole in it, but overall the glass is left largely intact. However, a low-speed... more
Why does a billiard ball stop when it hits another billiard ball head on?
(*I'm repeating myself a lot here, but it's because I want to make my confusion clear.*) If 2 billiard balls are the same exact mass, and one hits another stationary one head on, I have heard that... more
Impulse and force
I've been stuck on this question forever and I keep getting it wrong :( Please help! A truck of mass 3 tonnes is travelling at 105km/h when it hits a car of mass 1.5 tonne travelling in the... more
Finding velocity after a collision
On a very wet and slippery rugby field a 120 kg halfback tackles a 90 kg second rower. Prior to the collision the halfback is slipping with a velocity of 5.6m/s south and the second rower is... more
A car of 1 tonne travels at a speed of 100km/h collides with a 3 tonne van travelling 20km/h in the same direction. After the collision the car rebounds at 20km/h. Calculate the impulse on the van.
A rubber stopper collides inelastically with the ground. during the collision, the magnitude of the force exerted on the stopper is F(t)= 2x10^5t-3x10^7t^2 the collision last for 6.67 ms calculate... more
Rotational physics problem
a 1.5kg uniform rod of length .75 meters swings from rest around an axis through its end through an angle of 60 degrees. It strikes the center of a small .25 kg ball which sits on the edge of a... more
