**Can you answer this for me pls? I need this tomorrow and I still have so much work in hand. This questions are about Kinematics. pls help me.**

__with solutions pls__:)• The World Trade Center and the Empire State Building in the “Big Apple” have heights of 417 m and 381 m respectively. If objects were dropped from the top of each, assuming free fall,

**(a)**what would be the difference in time of their reaching the ground?

**(b)**What initial velocity should be imparted on the later object to reach the ground so that both objects will have the same times of fall and therefore strike the ground at the same time?

• Eunice throws a volleyball ball vertically upward with an initial speed of 9.8 m/s. Another student , Elaine, standing 5.0 m away, starts running toward the ball upon release and catches it at the same height of release. What was the horizontal acceleration of Elaine? (Assume uniform acceleration.)

• A kangaroo jumps to a vertical height of 2.7 m. How long was it in air before returning to the ground?

• The famous British spy, James Bond, is standing on a bridge 20.0 m above the railway and his enemies are getting too near for his capture. At that moment, 1/10 of a 100.0 m long high-velocity train is passing at 10.0 m/s under the bridge with an acceleration of 2.0 m/s2. For his escape, he jumped from the bridge towards the top of the train. Will his timing and the time of the passing train be a perfect escape factor to enable his landing on the last 1/10 m of the escape train? Prove your answer.

• Prince Juan found the Quetzalcotl asleep at the top of a tall kapok tree. The exhausted prince sits belowground to wait for the bird to wake up. Unfortunately, the sleeping bird release its dropping, which lands on Prince Juan’s unprotected head after 2.8 s.

**(a)**Assuming the dropping fell freely without impediments, what is the bird dropping’s speed just before hitting Prince Juan’s poor head?

**(b)**Find the location (dy) of the Quetzalcotl from the top of Prince Juan’s head.

• A student at a window on the second floor of a dormitory sees her archenemy coming along the walkway on the side of the building. She drops a water balloon 18.0 m above the ground when her enemy is 1.00 m from the point directly beneath the window. If the hated enemy is 1.70 m tall and walks at a rate of 0.450 m/s, does the balloon hit his head? Prove your answer.

• A photojournalist is on assignment documenting the search and rescue mission for the missing helicopter carrying a senator and team off the coast of some island. She accidentally drops her camera when the helicopter she was riding is 60.0 m above the ground.

**(a)**Assuming there is no air resistance, how long will it take the camera to reach the water?

**(b)**If the camera is shockproof to impact speeds of 200.0 m/s on water, will the camera be shattered?

• Juliet’s balcony is too high for Romeo to climb into. Desiring to catch the attention of a forlorn Romeo below, Juliet threw a pebble downward with an initial speed of 5.40 m/s from a height of 12.0 m above the ground.

**(a)**How far does the stone travel in 5.00 s?

**(b)**What is its velocity when it hits the ground?
