-Thrown Down -Going Up and Coming Down Physics Mr. Berman

Thrown Down A basketball is bounced straight down from a height of 1.2m with an initial velocity of 15m/s down. a)What is the final velocity of the ball? b)For how much time was the ball falling? Answer: a)-15.8m/s, b) 0.08s

Going Up Object is thrown upwards with an initial velocity in the +y direction Motion in y axis  constant acceleration g=-10m/s2 Symmetry

Going Up and Coming Down Symmetry vup = - v down tup = t down

Going Up Demonstration Link

Example 1 A tennis ball is thrown up from the ground with an initial velocity of 25m/s. a)At what time will the ball reach the top and what was the total time of flight? b)What is the maximum height? c)With what velocity did the ball reach the ground? Answer: a) 2.55s, 5.1s, b) 31.9m, c) -25m/s t=2.5s y=31.25m

Example 2 A rock is thrown straight up and reaches a maximum height of 20 m. a)What was the initial speed of the rock? b)What was the time it took for the rock to reach the top? Answer: a) 20m/s, b) 2s v initial= 20m/s t=2s

Going Up and Coming Down A ball is thrown straight up from a 100m tall cliff with an initial velocity of 3 m/s. What is the velocity with which the ball fell in the water? Answer: 44.4m/s
