A massive stone and a stone of one-half the mass are dropped from a tall building at exactly the same time. (Assume air resistance is negligible.) When both stones reach the ground: Will heavier mass play a factor in above?

How long does it take for a 0.25 kg stone to hit the ground if it dropped from a height of 60 meters?

a 925-kg pick up decelerates to rest from a speed of 97.5 km/h in a distance 125 m. Suppose the pick up is initially traveling in the positive direction. suppose instead of breaking that the pick up hits a concrete abutment at full speed is brought up to a stop at 2.0 m. Calculate the force in newtons exerted on the pickup in this case.

A car accelerates from a stop to 100km/h in 4 seconds.  - what is its acceleration? - what if it went from 100km/h to a stop in 5 seconds, what would be its acceleration? - suppose the car has a mass of 1200kg. How strong is the force on the car?

Ignoring air drag, the rocket will travel a distance of m further before reaching its maximum height. (Record your answer in the numerical-response section below.) Your answer: 0000 11. A toy snowmobile has a mass of 21.0 kg and a velocity of 94.0 m/s directed at 10.0° N of E. The component of the snowmobile's momentum in the North direction is kg-m/s. (Record your answer in the numerical-response section below.) Your answer: 0000 Use the following information to answer the next three questions Object 1 with a mass of 4.80 kg, moving right at a speed of 8.60 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.70 kg moving left at a speed of 10.8 m/s. After the collision, the Object 1 is moving left at 2.20 m/s. 12. The final speed of object 2 would be m/s. Answer to 3 sig digs. (Record your answer in…
