Question

Your friend is about to drive away after moving out and you notice that they left behind their basketball, so you decide to throw it at a 45 degree from the horizontal towards the truck. If the truck is 7.3 m away from you, at what speed must you throw the ball for it to make it into the truck? Assume you launch the ball at the same height as the truck bed.

Report the value in m/s rounded to the nearest tenth.

A battleship is testing its cannon out on open waters, tilting it 50 degrees above the horizontal. The cannon is 6.1 m above the sea level, and the cannonball is fired at 240 m/s. How long it will take the cannonball to reach sea level after being fired from the cannon?

Report the value in seconds rounded to the nearest tenth.

A stunt double must run horizontally off of the roof of one building, to another building 2.7 m away and 4.9m below. At what speed must they run to just barely make it onto the lower roof?

Report the value in m/s rounded to the nearest tenth.

You throw a ball for a dog to catch at a speed of 11.3 m/s, and an angle of 40 degrees to the horizontal. If the dog is initially next to you, dashes when you throw and catches it at the same height at which it was launched, for how long did the dog run?

Report the value in seconds rounded to the nearest hundredth.

A hockey puck is traveling with a velocity of 4.9 m/s to the right (0). In a slap shot which took 75ms, a hockey player hits the puck and causes it to move 5.3 m/s to the up (90). What is the magnitude of the average acceleration of the hockey puck?

Report the value as an integer in m/s2.
