You place a crate of mass 35.1 kg on a frictionless 4.90-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.37 s after you released it. What is the angle of the incline? 41.9 degrees 62.9 degrees 37.1 degrees 32.2 degrees

A stack of two crates is being accelerated upwards by two cables. The cables are directly attached to crate 1 and the tension in each cable is 3248 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. The acceleration of the crates is? bottom crate crate 1 is 109 kg. the top crate is 248 kg.

A person weighing 935. N rides in an elevator that has a downward acceleration of 1.26 m/s2. What is the magnitude of the force (in N) of the elevator floor on the person?

A block of mass 19.00 kg slides down an inclined surface at an angle 0 = 65.0° with speed v. The surface and block have a coefficient of kinetic friction my = 0.15. Determine the acceleration of the block down the inclined surface. 40.96 m/s^2 27.93 m/s^2 15.71 m/s^2 8.26 m/s^2

A woman pulls a cloth out from under a 200 g bowl sitting on a table. The bowl is 30.0 cm from the far edge of the cloth, and the cloth exerts a friction force of 0.125 N on the bowl. Assume the cloth is pulled with a constant horizontal acceleration of 2.80 m/s2. What distance (in m) does the bowl travel relative to the top of the table? (Assume the cloth moves in the +x-direction and notice that it moves more than 30.0 cm relative to the top of the table.)

A mover has to move a heavy sofa of mass 118 kg to the second floor of the house. He uses a rope to pull the sofa up a ramp from the first to the second floor. As he pulls the sofa he makes sure that the rope is parallel to the surface of the ramp which is at 30.0° to the horizontal. If friction between the sofa and the ramp is negligible, and the sofa has an acceleration of 0.700 m/s2, find the tension in the rope (in N). N

A 5-kg block is set into motion up an inclined plane (30°) with an initial speed of 8.0 m/s. There is friction between the block and the plane. The block comes to rest after traveling 3.0 m along the plane. Define the positive x-direction to be down the ramp.

You place a crate of mass 40.9 kg on a frictionless 2.64-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.52 s after you released it. What is the angle of the incline?      17.6 degrees      13.5 degrees      21.6 degrees      25.9 degrees

You place a crate of mass 43.2 kg on a frictionless 4.99-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.99 s after you released it. What is the angle of the incline?     17.9 degrees     14.9 degrees     20.9 degrees     25.1 degrees

If a mass of 3.46 kg object is attached to a string. If the force of tension in the string is 50.2 N j, what is the magnitude of the object's acceleration?
