Question
Бpeed 2
U of M,
cannon is fired from a cliff 110 m high
downward at an
angle of 27° with respect to the horizontal. If the
muzzle velocity is 34 m/s, what is its speed (in m/s) when it hits the ground?
34
Hint:
Use the projectile motion equations. Find the
y component of the initial velocity, and then solve the y problem for vy final. Then find the x component of the velocity; it doesn't change. The final speed is
v = (v,? + v,2)1/2
