An airplane with a speed of 76.6 m/s is climbing upward at an angle of 49.5 ° with respect to the horizontal. When the plane's altitude is 834 m, the pilot releases a package.
(a) Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth.
(b) Relative to the ground, determine the angle of the velocity vector of the package just before impact.
Explain how much work does the gravitational force do on the block as the block travels from point P to (a) point Q and (b) the top of the loop?
A block is placed at the end of the frictionless ramp and is pulled up the ramp through a solid ball on the end of a string that passes over a frictionless pulley that does not affect the motion of the block or ball. The ramp is 3.40 meters long and ..
