Question

jeff hits a baseball straight up in the air with an initial velocity of 38.0 m/s. how long does he stay in the air? find total time. how high does the ball go? find total travel? how fast does the ball #9 above? acceleration of famous race car driver is traveling at an initial velocity of 11.0 m/s for 5.00 seconds. how far does he travel in this time interval? alexis throws a metal ball downward with a velocity of 20.0 m/s from a tall building. if the height of the building is 500 m, with what velocity does the ball hit the ground? an electron in a vacuum tube is decelerated at a rate of -7.00 x 10^6 m/s^2. the speed of the electron after the deceleration takes place is 6.00 x 10^6 m/s. what is the speed of the electron before the deceleration? (this is an easy problem. list the givens and solve it!) alex is riding on a hot air balloon and is ascending at a rate of 24.0 m/s. he accidentally knocks his bologna sandwich out of the balloon while at an altitude of 200 m. calculate the total time the bologna sandwich was in the air. neglect air resistance. bonus vickie drops a heavy rock from a cliff 40 m above the water. it hits the water at a constant velocity. it continues to sink to the bottom of the lake at this constant velocity. it reaches the bottom of the lake 12 seconds after it was dropped. how deep is the lake?

Explanation:

The text describes various physics - based situations like motion of a rock, acceleration of an electron, and motion of a ball, but there is no specific query to solve for.

Answer:

Please clarify the specific question. The provided text seems to be a collection of physics - related scenarios but no clear question is stated.
