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 sliding...

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...

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 table...

A 3kg steel ball attached to a string is given an initial velocity of 1.8m/s and swings through an angle of 60 degrees, colliding with a 4kg steel cube also suspended by a string, initially at rest if...

A neutron of mass u traveling with a speed 5.00x105 m/s collides with a stationary alpha particle of mass 4u. The neutron scatters off the alpha particle at an angle 65˚ with...

Ball A of mass 5 kilograms moving at 20 meters per second collides with ball B of unknown mass moving at 10 meters per second in the same direction. A car traveling at 20 m/s has 1,000...

Bill forgets to put his car in park, and it starts rolling forward. When it is moving at a speed of 2 m/s, it collides with Tanya's car, which is moving 3 m/s backward. Bill's car bounces backward...

how would you solve a problem like this?

As a bus accelerates, the passengers on the bus are jolted toward the back of bus. Explain what causes the passengers to be apparently pushed backward.

Explain in which type of collision headrests serve the greater benefit: during a head-on collision or a rear-end collision?

Why would the rear-end collision demonstrated in the Investigate be more dangerous for someone driving a motorcycle than driving an automobile? Explain

A vehicle with a momentum of 6000 kg*m/s strikes a stationary vehicle. What is the momentum of two vehicles as they move off together after the collision? using physics terms please.

Two 1-kg carts are each moving toward each other at 2 m/s. They collide and each reverses directions, moving in the opposite directions at 2 m/s. Draw a diagram showing the carts before and after...

Describe the collision between two vehicles of very different masses moving toward each other at equal speeds in physics terms.

How is momentum conserved in a collision? Explain using words, calculations, or both as well as physics terms.

Ball A of mass 5 kilograms moving at 20 meters per second collides with ball B of unknown mass moving at 10 meters per second in the same direction. Which ball has more momentum before...

Ball A of mass 5 kilograms moving at 20 meters per second collides with ball B of unknown mass moving at 10 meters per second in the same direction. When is total momentum greatest...

Two safety dummies (of equal mass) are being used to test seat belts. Dummy A has a wide seat belt, and Dummy B has a narrow seat belt. Both dummies are crashed into a barrier while in the same car...
