a 15 kg television sits on a shelf at a height of 0.3 m how much graviitional potential energy is added to the television when it is lifted to a shelf of height 1.0m

A projectile proton with a speed of 500 m/s collides elastically with a target proton initially at rest. the two protons thenmove along perpendicular paths, with the projectile path at 60 from the original direction.

During the final stages of descent, asky diver with an openparachute approaches the ground with a constant velocity. Thewind does not blowhim from side to side.

A particle of mass m=5.00 kilograms is at rest at t=0.00 seconds. a varying force f (t) = 6.00t2-4.00t+3.00 is acting on the particle between t=0.00 seconds and t=5.00 seconds. find the speed v of the particle at t=5.00 seconds.

2. How is temperature related to kinetic energy?

As stream velocity decrease, which factor will likely increase? A) erosion of the stream bank B) deposition of material in the stream C) amount of material carried downstream D) size of the particles carried downstream

A mechanic pushes a 3.60 ✕ 103-kg car from rest to a speed of v, doing 5,130 j of work in the process. during this time, the car moves 21.0 m. neglecting friction between car and road, find v and the horizontal force exerted on the car.

Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?
