At time t-0 s, 0.80 s later, it reaches its maximum height a rock is thrown...
At time t = 0 s, a rock is thrown vertically upward from the ground. At time t = 1.6 s, it passes the top of a tall tower. 0.80 s later, it reaches its maximum height. Q)How fast is the rock moving as it passes the top of the tower? A car moving with constant acceleration covers the distance between two points 120 m apart in a time of 8.0 s. Its speed at the second point is 12...
A rock is thrown vertically upward from ground level at time t = 0. At t = 1.8 s it passes the top of a tall tower, and 1.2 s later it reaches its maximum height. What is the height of the tower?
A rock is thrown vertically upward from ground level at time t = 0. At time t = 1.4 s it passes the top of a tall tower, and 1.2 s later it reaches its maximum height. What is the height (in m) of the tower?
A rock is thrown vertically upward from ground level at time t = 0. At time t = 1 s it passes the top of a tall tower, and 1 s later it reaches its maximum height. What is the height of the tower? __ m
3. A ball is thrown straight up, reaches a maximum height, then falls to its initial height. Make a statement about the direction of the velocity and the acceleration as the ball is coming down. (1 mark) a) Both its velocity and its acceleration point upward b) Its velocity points downwards and its acceleration points upwards c) Its velocity points upwards and its acceleration points downwards d) Both its velocity and its acceleration point downwards. 4. A man stands on...
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...
A rock thrown vertically upward from the surface of the moon at a velocity of24 m/sec reaches a height of s=24t-0.8t^2 meters in t seconds.a) Find the rock’s acceleration and velocity at time t.b) How long does it take the rock to reach its highest point?c) How high does the rock go?d) How long does it take the rock to reach half its maximum height?e) How long is the rock aloft?
A rock is dropped from a height of 110 meters above the ground. One second later, a ball is thrown vertically downward from the same height with an initial speed of 14 m/s. A. At what time after the ball if thrown are the two objects at the same height above the ground? B. What is the speed of the rock when the ball hits the ground?
