A student is skateboarding down a ramp that is 5.02 m long and inclined at 23.6° with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp is 2.34 m/s. Neglect friction and find the speed at the bottom of the ramp.
A 14 kg block measures 7 cm by 9 cm by 25 cm. When it slides on a 9 cm by 25 cm face, it moves with constant speed when pulled horizontally by a force whose magnitude is 17 N. How big a horizontal force must be applied to pull it with constant speed if it slides on a 7 cm by 25 cm face?
A 4.40–kg block is set into motion up an inclined plane with an initial speed of vi = 7.60 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of θ = 30.0° to the horizontal.

Then the mass is pulled up an incline that makes an angle θ = 39° with the horizontal and has a coefficient of kinetic friction μk = 0.37. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 39° (thus on the incline it is parallel to the surface) and has a tension T =58 N. What is the work done by friction after the block has traveled a distance x=2.6m up the incline? The work done by gravity? I emailed my professor and he said to take the x=2.6m as the distance traveled along the ramp but I don't know what I am supposed to do with that.arrow_forwardSally wants to hang up some decorations on the side of her house, so she props up a ladder of length L = 3m against a wall at an angle of θ = 50° with respect to the horizontal. The ground is somewhat icy, where the coefficient of static friction between the ground and the ladder’s feet is µ = 0.55; while the wall of her house can be considered frictionless. If Sally has a mass of 60kg and the ladder has a mass of 80kg, what is the max distance that she can climb up the length of the ladder without it slipping? You may assume the ground is perfectly flat, and the wall is perpendicular to the ground.arrow_forward

There is some friction present; the kinetic coefficient of friction is 6.00×10-2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity.
