A stone is projected vertically upward from the top of a 120-m high tower at a initial velocity of 36 m/s. What is the vertical distance between the stone and the ground after t = 9 seconds? O 46.70 m O 73.30 m O 166.70 m O 193.30 m

You throw a 19.6-N rock vertically into the air from ground level. You observe that when it is 10.0 m above the ground, it is traveling at 20.0 m/s upward. What is the rock's initial speed as it left the ground? 32.4 m/s O 14.0 m/s 24.4 m/s 30.4 m/s O 17.3 m/s

A cannon is mounted on a tower above a wide, level field. The barrel of the cannon is 80 m above the ground below. A cannonball is fired horizontally with an initial speed of 800 m/s. Assuming air resistance can be neglected, approximately how long will the cannonball be in flight before it hits the ground? О 16 s 40 s 4 s 32 s 2 s About how far from the base of the tower will the cannonball land? 3000 m 800 m O 160 m 40 m 60000 m

You launch a projectile horizontally from a building 35.2 m above the ground at another building 23.2 m away from the first building. The projectile strikes the second building 9.7 m above the ground. What was the projectile s launch speed?     10.18 m/s     8.66 m/s     16.50 m/s     20.63 m/s
