The ball is thrown vertically upward at a speed of 10 m / s. What is the maximum height for the ball to climb? How long will it take him for this? How long does it take for the ball to hit the ground after it starts moving? Plot the graphs of the dependence of the projection and the modulus of the ball’s velocity on time, assuming that the Y axis is directed vertically up
Decision:
mgh = mv˄2; 2
10h = 100: 2
10h = 50 h = 5 m
5 = 10t – 5t˄2
5t˄2 -10t + 5 = 0
t = 1 s
t3 = 2t = 2c
Answer: 5m; 1c; 2c.
