1. [#361a] How much room does a juggler need? (part 1) 1 point A juggler throws balls almost vertically
upwards, with time At = 0.23 s between each throw. (Yes, pretty amazing.) The balls are all thrown to the
same height, and in repeated succession (e.g. 1, 2, 3, 1, 2, 3 etc.). Let's simplify: neglect air r...

4. [#363a] The big plunge (part 1) 1 point 3m 10 m 10 m You've made it to the top deck on the diving
tower, 10 m above both the ground level deck and the water, and 3 m wide, as in the diagram above (not
to scale). Your friend has dared you to run and jump horizontally, so as to go as far forward...

1. [#361a] How much room does a juggler need? (part 1) 1 point A juggler throws balls almost vertically upwards, with time At = 0.23 s between each throw. (Yes, pretty amazing.) The balls are all thrown to the same height, and in repeated succession (e.g. 1, 2, 3, 1, 2, 3 etc.). Let's simplify: neglect air resistance, neglect the time between catching and throwing a ball and assume that balls are thrown and caught at the same height. Calculate the minimum height he must throw the balls if he is to juggle 3 balls? m (Hints: How many throws before the same ball gets thrown again? How does the time for the ball to go up compare with the time to go down?) Enter answer here 2. [# 361b] How much room does a juggler need? (part 2) Using the information from question #361a above: Calculate the minimum height he must throw the balls if he is to juggle 5 balls? m (Hints: How many throws before the same ball gets thrown again? How does the time for the ball to go up compare with the time to go down?) Enter answer here 3. [# 362] Football on the moon Suppose that an astronaut, wearing a space suit on Earth, can kick a ball a distance of 25 m (have you tried kicking in a space suit?). Using the datum gravitational acceleration is gmoon = 1.6 m.s, estimate how far he could kick the ball on the moon, using the same action and kicking at the same angle. (Remember significant figures and neglect air resistance. Assume that the launch and landing heights are the same. Do not use exponent notation.) m Enter answer here 1 point 1 point
