A rock is thrown straight up and passes by a window. The window is 1.7m tall, and the rock takes 0.19 seconds to pass from the bottom of the window to the top. How far above the top of the window will the rock rise?

10. A ba is thrown straight up and passes a window in a multi-story building. The window is 2.0 m tall. A person in the room looking out of the window sees the ball move past but it disappears for a brief interval of time and then it reappears as it falls back down past the window. The person sees the ball for a total of 0.80 sec (0.40 sec going up and 0.40 sec going down). Find the height...
A ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 0.312 s to go past the window. What was the ball's initial velocity? Next, consider only the distance from the ground to the bottom of the window, and solve for the initial velocity using the velocity at the bottom of the window as the final velocity.
A ball is thrown upward from the ground. You observe the ball through a window on its way up, and notice that it was visible for 1 seconds while it travels from the bottom of the window to (a) How far above the top of the window will the ball reach, in metres?
A ball is thrown upward from the ground. You observe the ball through a window on its way up, and notice that it was visible for 1 seconds while it travels from the bottom of the window to the top, which is a length of 17.805 metres. (a) How much time does it take for the ball to be seen again, in seconds? (b) How far above the top of the window will the ball reach, in metres?
A ball is thrown straight down at 1.50 m/'s from a tall tower. Two seconds (2.00 s) later a second ball is thrown straight up at 4.00 m/s. How far apart are the two balls 4.00 s after the second ball is thrown? Ignore the effects of air resistance. Example 2-9
A rock is thrown straight downward from a tree limb with an initial velocity v_0. The rock has constant downward acceleration of 10 m/s^2 during its fall. The rock moves 6 times as far during the first 4 seconds as during the first 1 second of tall. What is the value (magnitude only) of v_0?
A rock takes 3.2 s to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.4 m/s. Calculate the height of the cliff (in meters). Using that information, how long would it take to reach the ground if the rock is thrown straight down with the same speed?
A rock takes 2.40 s to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.17 m/s. How long (in s) would it take to reach the ground if it is thrown straight down with the same speed?
It takes 0.117 s for the rock to pass by a 1.80-m high window. How far from the top of the building is the top of the window? (Express your answer to three significant figures.)
Two rocks are thrown from the top of a very tall tower. One of them is thrown vertically up with an initial velocity of Vup=19.7 m/s. The other rock is thrown horizontally to the right with an initial velocity of Vright 12.7 m/s. (See figure.) How far will the rocks be from each other after 2.76 s? (Neglect air resistance and assume that the rocks will not hit the ground or the tower.)
