The crate has a mass of 50 kg and the coefficient of static friction between the crate and the plane is µs =0.25.

(a)determine the minimum horizontal force p required to hold the crate from sliding down the plane.
(b) determine the minimum force p required to push the crate up the plane

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
