What is the kinetic energy of a 2000 kilogram boat moving at 5m/sec?

An athlete whose mass is 87.0 kg is performing weight-lifting exercises. Starting from the rest position, he lifts, with constant acceleration, a barbell that weighs 600 N. He lifts the barbell a distance of 0.65 m in a time of 1.3 s.

How is plastic deformation related to high temperature and pressure?

If we decrease the amount of force, and keep all other factors the same, what will happen to the amount of work? A: the amount of work will go down because the distance will decrease.

Why do star clusters make superbubbles? Why do star clusters make superbubbles?

What effects gravitational force between objects

If a car drove 121km/hr on average how far did it travel in 116min?

A 10 kg farm wagon is sitting at the top of a hill that makes a 370 angle with the horizontal when the brake suddenly fails. The cart rolls down the hill for 50 m and then hits a haystack. It plows 2.0 m into the stack before coming to rest.

What is a Geographic test

What is the velocity of a beam of electrons that go undeflected when passing through crossed (perpendicular) electric and magnetic fields of magnitude 1.63*104V/m and 2.50*10-3T, respectively? me=9.11*10-31kg, e=1.60*10-19C.

Gravity pulls gases and dust particles in space toward one another, squeezing them into a smaller and smaller space. The temperature at the center rises high enough for fusion of hydrogen to begin.
