Projectile motion Exercises A ball is thrown skywards with an initial vertical velocity of 24 m/s and an initial horizontal velocity of 10 m/s as shown on the right. Ignore air resistance a) What is the initial velocity of the ball? b) How long does the ball take to reach its maximum height? Assume g=10m/s/s/. c) What is the maximum height reached by the ball? d) How far does the ball land from the thrower? e) What is the magnitude of the velocity of the ball at "A"? Solution A ball is thrown skywards with an initial vertical velocity of 40 m/s and an initial horizontal velocity of 8 m/s as shown on the right. Ignore air resistance a) What is the initial velocity of the ball? b) How long does the ball take to reach its maximum height? c) What is the maximum height reached by the ball? e) What is the balls vertical acceleration? f) What is its horizontal acceleration? g) At what point along its path does the ball have minimum speed? Solution A ball is hurled horizontally off the table with a velocity of 20m/s while another identical ball is allowed to fall, from the top of the table to the floor. Which ball strikes the ground first? Solution Explain why? Solution Continue
