17. a 1350 g projectile is launched with a force of 150 n. the length of the firing arm is 1.25 m.
a. determine the exit velocity of the projectile.
b. determine the maximum height the projectile achieved
c. what is the total time the projectile travelled?
d. determine the distance the projectile travelled if the launch angle is 42 degrees from the horizontal
and the target is 27 meters below the launcher.

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
