An athlete performing a long jump leaves the ground at a 31.8 ∘∘ angle and lands 7.65 mm away. What was the takeoff speed? Express your answer using three significant figures and include the appropriate units. If this speed were increased by just 4.0%, how much longer would the jump be? Express your answer using two significant figures and include the appropriate units.
the leprechaun in the shamrock patch was named O'Malley and since he was disrupted from sitting in his patch he decided to go off and play a round of his favorite sport in where leprechaun kick a gold coin from a tee into a post 317m away. if he kicked the coin at an angle of 60 degree at a velocity of 60 m/s how high was the arch of the rainbow created by the trajectory? how long did it take to get to the pot? the officials in dublin decided to add a goal post to "kick O coin" 300 meters away and so many 33 meters high. would O'Malley's kick have cleared this goal post?

A child in Yellowstone National Park kicked a rock off a bridge down into a river below. The bridge had a height of 405 meters above the river. If the child kicked the rock with an initial velocity of 2.1 m/s, What was the amount of time required for the rock to hit the river below? How far horizontally from the bridge did the rock travel?
