  1. A projectile is launched from a projectile launcher as shown. The projectile is fired at a height h above level ground. While in the barrel of the projectile launcher, the projectile has a constant acceleration over the length d, leaving the launcher with speed S.

Solve the following (a-d) in terms of given variables and fundamental constants. Meaning parts (a-d) must be answered in terms of the following variables: h, d, S, Θ.

  1. What is the acceleration of the projectile while in the launcher?
  2. What is the time required to reach maximum height?(assume the time in the projectile launcher is negligible)
  3. What is the maximum height relative to the ground?
  4. What is the speed of the projectile at maximum height?
  5. Draw vectors for the velocity and acceleration of the projectile at point A and B.
  6. Neglecting air resistance, how will the speed (S) of the projectile as it leaves the launcher, compare to the speed just before impact with the ground.Justify your answer.

  1. With the absence of an NHL season, EvgeniMalkin has resorted to doing physics calculations in Russia to pass the time. Shooting a puck across a large lake, he records the distance the puck slides across the ice, along with the respective time.

a)Construct a linear graph by manipulating the data. Label your graph axis.

b)Determine the acceleration of the puck from your data set.

c)How far would a puck travel that is shot at 50m/s?

d)Describe the general relationship between the velocity the puck is shot across the ice and the distance the puck will travel.
