Question 5 15 marks You should be able to answer this question after studying Unit 10 A crate, initially at rest, is pushed along a straight line up a rough ramp that makes an angle of 18° with the horizontal. The magnitude of the pushing force is 33 N, in a direction parallel to and up the ramp, and the acceleration of the crate is 0.16 ms-2. The coefficient of sliding friction between the crate and the ramp is 0.35....
A 40 kg crate is pulled 50 m along a horizontal floor by a constant force exerted by a person, Fp = 150 N, which acts as 30 degree angle. The floor is rough and exerts a friction for Ff = 40 N. Determine: a) the work done by each force acting on the crate b) the net work done on the crate
6.7: A worker pushes a 40 kg crate at a constant speed of 10 ms/ along a level floor by exerting a force on it that is inclined 30∘ below the horizontal. If the coefficient of kinetic friction between the floor and the crate is 0.2 , what is the net work done by all forces acting on the crate after the worker has pushed the crate a distance of 40 m ?
A crate of mass m = 1.12 kg is on a frictionless incline that makes an angle of θ = 27.6 degrees with horizontal. A force of magnitude P = 7.24 N is applied to the crate in a direction parallel and up the incline, as shown. Write an expression for the acceleration ax of the crate, where positive x is up the incline. Your answer should be in terms of m, P, θ, and g (9.80 m/s2).
Problem 5: A block with a mass of m=37 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x-direction with a magnitude of F1=8.5 N.
