A first stone is dropped from the roof of the building. 2s later a second stone is thrown straight down with an initial speed of 30 m/s. It is observed that both stones strike the ground at the same time. Determine the taken for the stones to strike the ground and the height of the roof from the ground.

Question 3 (2 objects 2 accelerations) Two cars are lined up for a drag race. On start, both cars accelerate with different constant acceleration. When car A reaches the finish line 200 meters away, car B is 80 meters ahead of car A traveling at 50 m/s. a. How much time did the race take? b. What was the acceleration of car B? c. What was the acceleration of car A? d. How fast was...
At t = 0, a stone is dropped from a cliff above a lake; 2.4 seconds later another stone is thrown downward from the same point with an initial speed of 35 m/s. Both stones hit the water at the same instant. Find the height of the cliff in meters.
If you drop a stone from the top of a building, and at the same time your fire a tennis ball horizontally from the same height, which object will hit the ground first? ignore the air resistance. a. The stone b. The tennis ball c. The same time d. not sure
At t = 0, a stone is dropped from a cliff above a lake; 2.4 seconds later another stone is thrown downward from the same point with an initial speed of 47 m/s. Both stones hit the water at the same instant. Find the height of the cliff.
Two identical objects are dropped from rest at the same time. Object A is dropped from twice the height of object B. If there is no air resistance, which statement is true? None of the answers given is true. Both objects hit the ground at the same time. Object A takes twice the time to fall as object B. Object A takes four times the time to fall as object B.
A stone is thrown upwards from the top of a building an initial height 11 m above the ground with a velocity of 6 m/s. (4 marks) Calculate i) The maximum height above the building the stone reaches ii) The time it takes the stone to hit the ground iii) The distance the stone travels iv) The displacement the stone undergoes
A stone is dropped from the roof of a building; 1.90 s after that, a second stone is thrown straight down with an initial speed of 27.0 m/s , and the two stones land at the same time. A) How long did it take the first stone to reach the ground? B) How high is the building? c) What are the speeds of the two stones just before they hit the ground? Enter your answers numerically separated by a comma.
