a rocket is launched upward from the ground with the initial velocity of 35 m/s . The magnitude of its acceleration is 5.0 m/s² . suddenly the engine breaks down at height h = 20km from the ground . neglect air resistance . calculate the speed of the speed of tge rocket at height 20km

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.
