garden hose sprays a burst of water horizontally from 1.6 m above level ground. It hits a fence 2.1 m away, horizontally, at a height 0.93 m above the ground. What was the initial speed of the burst of water?

Sofia is playing a game with her friend, Kara, where she throwsM&M candies at Kara and Kara catches the M&M’s in hermouth. They begin standing 1.75 meters apart from eachother. Sofia throws the M&M at an angle of 60 degrees abovethe horizontal with a speed of 4.13 m/s. Kara’s mouth is145 cm above the ground when she catches the M&M. Whatheight above the ground did the M&M leave Sofia’s hand?Hint: Remember, even though the motion in the horizontaldirection is independent of the motion in the vertical direc-tion, they share the same time.

Use g = 10 m/s/s.

A mortar shell has an initial velocity v0= 13 m/s, at an angle θ0=60º.  At the maximum height of the trajectory the shell explodes into two equal pieces.  One piece has a speed immediately after the explosion of zero then falls vertically.  How far horizontally does the other fragment land from where it was fired.
