What is the kinetic energy of a toy truck with a mass of 0.75 kg and a velocity of 4 m/s? (formula: )

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

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.
