Question
A cannonball is fired with an initial speed vị =
150 m/s at an angle 0
ground. See Figure 3.
= 50° with respect to the
0 = 50°
m
a) What are the x and y components of the
initial velocity?
Figure 3
b) What are the x and y components of the velocity when the cannonball is at the apex (the
highest point) of its trajectory?
c) On its ascent (moving upwards), how long will it take the cannonball to reach a height of
400 m?
