A ball is thrown horizontally from the top of a 60.0-m building and lands 100.0 m from the base of the building. Ignore air resistance. (a) How long is the ball in the air? (b) What must have been the initial horizontal component of the velocity? (c) What is the vertical component of the velocity just before the ball hits the ground? (d) What is the velocity (including both the horizontal and vertical components) of the ball just before it hits the ground?
Step 1 of 7
Ball is thrown horizontally from a building of height and it reaches the ground at a distance of from the build as shown in the figure below. Here we need to calculate using kinematics equations, the time taken by ball to reach ground , the horizontal initial velocity of ball , the final vertical velocity of ball just before reaching ground and the final velocity of the ball just before it hits the ground .
