An object is thrown vertically upwards with initial speed 15m/s. After 1s, a second object is thrown up. What is the initial speed that the second object must have to hit the first object at a height of 11m?
An object is thrown vertically upwards with initial speed 15m/s. After 1s, a second object is...
A ball is thrown vertically upwards at a speed of 15m/s at the edge of a 20m deep well. The ball is released at a height of 2m above ground level. How high does the ball rise above ground level? If the ball on its downward path falls down the well, how many seconds elapse between releasing the ball and it striking the bottom of the well? Assume that the downward acceleration is 9.81 m/s2 .
A stone is thrown vertically upwards with a speed of 20.0 m / s. (a) What is its speed when it reaches 18 meters? (b) What maximum height does it reach?
A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...
A ball is thrown vertically upwards with a speed of 20 m / s. (a) How fast is the ball when it is at a height of 15 m? (b) How long does it take you to reach that height?
An free falling object is thrown upwards with an initial velocity of 20.4 metres per second. How far up is it after a time of 3.1 seconds
2. A water balloon is thrown from the roof vertically upwards with initial speed o. It reaches some maximum height Hea then falls, and hits the ground 25 meters below the roof with the speed 2 times faster than the initial speed. (a) What is the initial speed Vy? (b) What is the speed it hits the ground? (c) What is the maximum height Ho? (d) How long does it take to reach the Ho?(e) How much total time does...
Two identical balls are thrown vertically upward. The second ball is thrown with an initial speed that is twice that of the first ball. How does the maximum height of the two balls compare? The maximum heights of the two balls are equal. The maximum height of the second ball is two times that of the first ball. The maximum height of the second ball is four times that of the first ball. The maximum height of the second ball...
A ball is thrown vertically upwards with an initial velocity of 27.0 m/s. Neglecting air resistance, how long is the ball in the air? Submit Answer Tries 0/99 What is the greatest height reached by the ball? Submit Answer Tries 0/99 Calculate the first time where the ball has half of its initial velocity
A stone is thrown vertically upwards with a speed of 20.0 m / s. (a) What is its speed when it reaches 18 meters? (b) What maximum height does it reach?
A ball is tossed straight upwards with an initial velocity of .30.00 metres per second from a height of 20,000 meters. Assume that the only force acting on the object is acceleration due to Earth's gravity. Write out the position and velocity functions. With what velocity does the object hit the ground? When the object hits the ground, it bounces back up with one-fourth the speed that it had when it hit the ground. Determine the height of the ball...
