- Dong and Rigo are playing their slingshot, both of them shot a pebble vertically upward. Rigo shot after Dong, but while the Dong’s pebble is still on its way up. The initial speeds are such that both pebbles reach their maximum height at the same instant, although these heights are different. Suppose that the initial speed of the Dong’s pebble is 40.6 m/s and that Rigo’s pebble is shot 1.25s after Dong’s, determined the initial velocity of the Rigo’s pebble.Part A If a flea can jump straight up to a height of 0.500 m, what is its initial speed as it leaves the ground? v= 3.13 m/s Submit Previous Answers v Correct Part B How long is it in the air? t= 0.32 Submit Previous Answers Request Answer X Incorrect; Try Again; 5 attempts remainingA student drops a ball from a height of 37.0m.
