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 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 upwards with a speed 11 m/s at an angle of 52o above horizontal. How much time before it reaches the top of its flight? Answer in seconds. Neglect air friction and use g = 9.8 m/s2 if needed. Pay attention to the way the angle is defined.
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
(Problem 2/10 from Meriam and Kraige Dynamics) 60 m A ball is thrown vertically up with a velocity of 36 m/s at the edge of a 60 m cliffa. Neglect air resistance and take the downward acceleration to be 9.81 m/s2, calculate: (a) the height h to which the ball rises; hNumber (b) the total time t after release for the ball to reach the bottom of the clioff tNumber (Problem 2/10 from Meriam and Kraige Dynamics) 60 m A...
