UGH! I've been working on this problem for about an hour now for my test tomorrow at WMU. No luck. =( My guess? Impossible. =P

physics
A 102.0 N grocery cart is pushed 13.0 m by a shopper who exerts a constant horizontal force of 54.0 N. If all frictional forces are neglected and the cart starts from rest, what is its final speed?

physics
a 0.1 kg mass is suspended at rest from a spring near the Earth's surface, the distance that the spring is stretched is measured to be 1.0 cm. What is the spring constant of the spring (remember the MKS units)? A mass of 2 kg is attached to a spring with constant 18 N/m. ...

1. An object of mass m and initial speed v0 sliding on a horizontal frictionless surface encounters a frictionless ramp. To what vertical height will the object rise before coming to rest?

physics
An object of mass m=2kg travels up an incline to a vertical height of 3m. What is the work done on the object by gravity?

physics
Will the work done by friction on an object that moves through a positive displacement be positive of negative??? negative

An object of mass m=2kg travels up an incline to a vertical height of 3m. What is the work done on the object by gravity?

Physics
0.17 kg point mass moving on a frictionless horizontal surface is attached to a rubber band whose other end is fixed at point P. The rubber band exerts a force F = bx toward P, where x is the length of the rubber band and b is an unknown constant. The mass moves along the dot...
