Alice tosses a ball straight up. After 2s it has reached a height of 5m measured from where the ball was launched.

i) What is the initial speed of the ball?

ii) Assume that Alice released the ball 1m above the ground. What is the maximum height of the ball?

iii) How long is the ball in the air?

iv) What is the velocity of the ball when it hits the ground?

Consider a ball being fired straight up (purely in the y-direction). If the ball has a maximum height of H above the launcher, you should be able to calculate the initial velocity of the ball, v0 , as it leaves the launcher. Answering the questions below will help you accomplish this task. First draw a diagram of the situation. Clearly label H , v0 , and the point you select as your origin. What will the velocity of the ball...

You toss a ball straight up. Let t = 0 be the time just after you throw the ball, let t = treturn be the time just before it the ball returns to your hand (motion is in free fall). The only knowns are treturn, g, H (max height), Viy. Use yf = yi+Viy(deltat) -(1/2)g(delta t)^2 to determine the two times when the ball is at half of its maximum height.
