Transcribed Image Text: A ball is thrown from an Initial height of 6 feet with an initial upward velocity of 36 ft/s. The drag force which affects the motion of the ball is represented as \[m\gamma {v^2}\] . So, in this case the maximum height reached by the ball is given by. This is only true if either t-10 = 0 or t+4 = 0 so t = 10 or t=-4, As stated, we can disregard t=-4. c. acceleration is zero but not its velocity. Considering the Air resistance or Drag force negligible, the only force acting on the ball is Gravity i.e. Assuming no air restance the speed when the ball comes back to the starting point will be again #8m/s# but directed DOWNWARDS; we can express this saying that it will equal to #-8m/s# adding a minus to indicate the downward direction. 3) As it goes up vertically, due to the weight acting downwards, the ball decreases in . container.style.maxWidth = container.style.minWidth + 'px'; Question: (17%) Problem 5: A ball is thrown upward from the ground with initial velocity vi = 18 m/s and reaches height of h above the ground before falling back down. c. Both balls reach the floor at the same time because they both have the same initial zero y-component of velocity. Hence, the total time duration for which the ball was in motion will be twice the above calculated time. So, we get: 4.20s. % To find the time of flight we use: #v_f=v_i+at# Where: #a# is the acceleration of gravity (downwards, #-9.8m/(s . Use g = 9.8 m/s2 (a) Find the maximum height above the ground that the ball reaches. Explanation: At the maximum height h, the final velocity of ball v becomes zero when thrown with an initial upward velocity u = 10 m s against the gravitational acceleration g = 9.81 m s2. Hence, the time duration in which the ball was in motion is. its velocity becomes zero at that height. B)When will the object hit the ground? How long will it be before the ball hits the ground? At the same instant an open platform elevator passes the 5 m level, moving upward with a constant velocity of 2 m/s. Upward movement and then a downward movement of a ball when a ball is thrown vertically upward this is what we will discuss here and as well as we will derive the equations of the vertical motion.
