A horizontal force F=60 N pushes a 3 kg block up a ramp. The ramp is inclined at an angle of 30 degrees to the horizontal and the coefficient of kinetic friction between the block and the ramp is 0.25. A) Find the acceleration of the block up the ramp.

A 99-kg box, initially at rest on a frictionless surface, accelerates for 2 s over a distance of 100 m while acted on by a constant horizontal force P. Find the magnitude of P. P = N

In a TV commercial pickup truck B of mass mB lifts large crate A of mass mA toawrd the top of a cliff by means of a cable and a frictionless pulley. The truck uses constant thrust force F to do the job and accerates forward starting from rest, There are no friction forces except the thrust force F.  a) Determine a symbolic formula for the magnitude of the acceration experienced by the crate. The final formula should not include the unknown tension force.  b) explain whether the cable tension must be greater than, equal to, or less than the crate weight.  c) for mass mA= 1500 kg, mb=2800 kg, and F=18,000N, how far will the crate rise in the first 3.5 s of motion?

Tom enlists the help of his friend John to move his car. They apply forces to the car. F1 = 430 N and F2 = 347 N and friction is negligible. Mass of car = 3500 kg O1= -25 degrees and O2 = 12 degrees (assume the car faces the positive x-axis before the forces are applied. A) Find the force (in N) exerted on the car     Magnitude =     Direction (counterclockwise from the +x-Axis) = ______________ degrees B) What is the acceleration (in m/s squared) of the car?     Magnitude =   __________ m/s squared     direction (counterclockwise from the +x-Axis) ______________ degrees
