A stone slab with a mass of 10 kg is fired out of a catapult at ground level that is tilted up at 45°. At the top of its flight parabola, the slab drags to a stop on a level rooftop with a kinetic friction coefficient of ½. Find the height of the building and the distance the slab skidded if the launch speed was 19.6 m/s. (Physics Question)
Homework Answers
Concept:- here we use the equations for
projectile motion to find the maximum height and then on the
rooftop we find the deceleration of the slab using friction force
on it,

This concludes the answers. If there is any mistake,
let me know immediately and I will fix
it....

A stone with mass m = 0.700 kg is thrown vertically upward into the air with an initial kinetic energy of 610 J. The drag force acting on the stone throughout its flight is constant, independent of the velocity of the stone, and has a magnitude of 0.600 N. What is the maximum height reached by the stone? What is the speed of the stone upon impact with the ground?

Th figure below shows a mass m=1.0 kg which is initially moving
with speed v=7.2 m/s at the top of a frictionless hill of height
h=4.9 m. It slides down the hill until it encounters a flat section
with unknown coefficient of kinetic friction µk. If the object
travels a distance D=11.1 m before reaching a speed of v/2, what is
the coefficient of kinetic friction µk? (use picture, but first

Suppose the vertical height h that Supergirl can jump after she compresses her tendons a distance x1 (beyond her unstretched length) is 25m. How high would she jump after she has compresses her tendons an additional 10% more than before (that is a distance 1.10x1 beyond her unstretched length)?
