A secret chamber is opened by applying a force of 300 N perpendicular to the plane of the door, 0.80 m from the hinges. Calculate the torque due to this force about an axis through the hinges. Round to two significant digits please. 

A merry-go-round turns at a constant rate of 6 complete rotations per minute. What is its angular speed in radians per second?

Assume a rotator’s angular position is given by , where and are constants. If at , t = 0 , rads/s and  rads/s2, what is the constant ? Three significant digits.

A secret chamber is opened by applying a force of 300 N perpendicular to the plane of the door, 0.80 m from the hinges. Calculate the torque due to this force about an axis through the hinges. Round to two significant digits please. 

An impulse enacted on a 2.0 kg particle results in the change in velocity according to the velocity versus time graph. Calculate . Use two significant digits.  

A particle is traveling along the positive x-axis with a momentum of 50.0 . It encounters an average force of    for a time of  s . Calculate the final momentum of this particle after the brief encounter. Use three significant digits.

A particle (particle 1) is traveling along the positive x-axis with a constant speed of 50.0 m/s. It collides head-on with an identical particle moving towards it with a speed of 39.0 m/s. If both masses are 1.0 kg, what is the final speed of the first particle just after the collision? Two significant digits.

A mass of 2.00 kg is released on top of a frictionless incline. The height if its release with respect to the ground is 25.0 m. Calculate the kinetic energy at the moment it reaches the ground. Three significant digits please.
