A2 kg bowling bowl is 1 meter off the ground on a post when it falls. just before it reaches the ground, it is travelling 4.4 m/s. assuming there is no air resistance, which of the following statements is true 1. the mechanical energy is conserved 2. the initial potential energy is less than the final kinetic energy 3. the initial potential energy is greater than the final kinetic energy 4. the mechanical energy is not conserved

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.
