A 98.0 kg hockey player skating at 2.12 m/s 32° S of W is body checked by an 87.0 kg opponent who is skating at 1.40 m/s 42° N of E. They collide inelastically and stick together. 1. What is the...

1. How much work would a 60.0 kg person do in climbing from the surface of the Earth to the top of a mountain 2.00 km high? a) Use EP = mgh to find your solution. Show all work. (ans. 1.18×106...

Given that the moon orbits the earth in 27.3 days compute the centripetal force acting on the moon.

I think that it directly affect the net force and indirectly affect the acceleration, range, maximum height and the launch velocity.

How far above the Earth’s surface must we be before “g” has decreased significantly by dropping 10%?

Imagine a 2 kg toy plane hanging from a string and moving in a horizontal circle of radius 2 m. The tension in the string is 50N. What is the speed of the plane? Start with a FBD and FNET = ma.

5. The mass of the planet Mercury is 3.30 x 10^23 kg and its radius is 2.439 x 10^6 m. What would a 65.0 kg person weigh on Mercury? What is the acceleration due to gravity on Mercury? (gravitational...

A water balloon is dropped on the bull's-eye target from a stationary hot air balloon. The water balloon is 353 m above the target. If the water balloon accelerates downward at 9.81 m/s squared, how...

A 9.10 kg particle is subject to a net force that varies with position as shown in the figure. The particle starts moving at x = 0, very nearly from rest. http://www.webassign.net/pse/p7-17...

When a spring is compressed by 0.28 meters it stores 33 Joules of elastic potential energy. Find the spring constant. please help :) thank you

A toy car with mass of m=136 GRAMS crashes into a spring with constant k=37 N/m. If the car was going v=1.93 m/s, then how far will the spring compress? In your answer: respond in terms of meters...

A student with mass 66 kg runs up a flight of stairs that's 4.7 meters high. It takes him 4 seconds to move from the bottom to the top of the stairs, and we'll assume his KE is essentially zero at...

An electric wheelchair encounters a resistance force of 302 Newtons. The motor for this wheelchair can output mechanical energy with a power of, at most, 1398 Watts. What is the maximum speed with...

Two packing crates of masses m1 = 10.0 kg and m2 = 6.50 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.26. The 6.50 kg crate lies on a smooth incline of...
