An object of mass 2 kg is held at the top of a triangular wedge, and then released. The reference level for potential energy is at the base of the triangle. Neglect friction and use g=10m/s^2. Height of triangular wedge=3m width of triangular wedge=4m. What is the amount of work done by the gravitational force as the object comes to the bottom of the wedge? Also, what is the speed of the object just before it reaches the bottom of the wedge?

I need homework help 1. A physical scicence test book has a mass of 2.2 kg What is the weight on the earth? 2. Whar is the weight on Mars (g = 3.7 m/s2) 3. If the textbook weighs 19.6 newtons on Venus, what is the strength of gravity on venus? 4. Of all the planets in our solar system, Jupiter has the greatest gravitational strenght. If a 0.5 kg pair of running shoes would weigh 11.55 newtons on Jupiter, what is the strengh of gravity there? 5. If he same pair of shoes weighs 0.3 newtons on Pluto, what is the strenght of gravity on pluto? 6. what does the pair of shoes weigh on earth? Big Big Thanks for any help!!
A 60.0-kg person is in an elevator with a mass of 2000 kg. The elevator moves vertically up through a distance of 24.0 m with a constant speed of 4.00 m/s. How much work is done on this elevator system? Use g=10.0m/s^2.
