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?

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

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...
A projectile is launched with an initial speed of 60 m/s at an
angle of 35° above the horizontal. The projectile lands on a
hillside 4.0 s later. Neglect air friction. (a) What is the
projectile's velocity at the highest point of its trajectory? m/s
(b) What is the straight-line distance from where the projectile
was launched to where it hits its target? m
A projectile is launched horizontally with an initial speed of
v0 = 38.5 m/s at the top of a cliff in a lake (h = 80 m) What is
the speed of the projectile when its height from the water is y =
30 m?
