A 50.0-kg crate is being pulled along a horizontal, smooth surface The pulling force is 10.0 N and is directed 20.0" above the horizontal What is the acceleration of the crate? An object of mass 25 kg, attached to an ideal massless spring, is pulled across a frictionless surface. If the spring constant is 100 N/m and the spring is stretched by 0.5 m, calculate the acceleration of the object when released.

1. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume the...

1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....
