the weight of the crate is acting vertically downwards and the value will be,
the normal reaction of the box with the plane will be
so the frictional force will be,
A)
the acceleration component along the plane will be
but the opposing frictional force will reduce this to
B)
using eqn of motion, ,
and u = 0 initially
and s = 8.25m
we have
PHYS 1441 Spring 2019 Assignment (Part 2) Problem C42-07 The crate shown in (Figure 1) lies...
The crate shown in (Figure 1) lies on a plane tilted at an angle θ = 21.5 ∘ to the horizontal, with μk = 0.19. Part A :Determine the acceleration of the crate as it slides down the plane. Express your answer to two significant figures and include the appropriate units. PartB: If the crate starts from rest 8.30 m up along the plane from its base, what will be the crate's speed when it reaches the bottom of the...
