17.You launch a projectile at an initial speed of 45.8 m/s from the ground. After 3.30 seconds of flight, the projectile lands on the ground. At what angle above the horizontal was the projectile launched?

		15.6 degrees
		20.7 degrees
		31.1 degrees
		11.5 degrees

18.A projectile is fired from the ground, reaches a maximum height of 56.4 m and lands a distance of 39.0 m away from the launch point. What was the projectile s launch velocity?

		33.3 m/s, 40.1 degrees above horizontal
		5.8 m/s, 48.1 degrees above horizontal
		57.5 m/s, 24.1 degrees above horizontal
		33.8 m/s, 80.2 degrees above horizontal

A projectile (with mass 300g) is launched with an initial speed of 30 m/s at an angle of 32 degrees above the horizontal from the edge of a 20 m tall cliff. At the point in the trajectory where the projectile was at its maximum height, a 25g projectile is launched straight up into the first projectile. The smaller mass is traveling at 300 m/s and the two objects stick together. Calculate the percentage increase in height and total horizontal...
