Can anyone please work out the projectile motion questions?
1 Answer
a)
b)
c)
d)
e)
Explanation:
Given:
Initial velocity of projection:
Angle of projection
a)
Horizontal component of the initial velocity
Thus,
b) Maximum height reached by the ball
Vertical component of the initial velocity
c) Time of flight of the soccer ball.
initial vertical velocity is
final vertical velocity is
Change in velocity is
Final velocity - initial velocity
Acceleration due to gravity is
Acceleration during the journey is
Time of flight is
d) Range of the soccer ball
Acceleration along horizontal direction is zero
Range of the soccer ball is
e) Velocity of the soccer ball after time t = 1.2 s
Same for the entire journey
Substitute t=1.2s
