Now let's consider the impulse associated with kicking a soccer ball (Figure 1). The ball has mass 0.40 kg . Initially it moves horizontally to the left at 20 m/s, but then it is kicked and given a velocity with magnitude 30 m/s and direction φ=45∘ upward and to the right. Find the impulse of the force and the average force on the ball, assuming a collision time Δt=0.010s a) Suppose the ball is moving at 30 ∘ downward from the horizontal before it is kicked. If all the numerical values are the same as before, find the magnitude of the average force on the ball. b)Find the direction of the average force on the ball found in Part A.

Question
Now let's consider the impulse associated with kicking a soccer ball (Figure 1). The ball has mass 0.40 kg . Initially it moves horizontally to the left at 20 m/s, but then it is kicked and given a velocity with magnitude 30 m/s and direction φ=45∘ upward and to the right. Find the impulse of the force and the average force on the ball, assuming a collision time Δt=0.010s
a) Suppose the ball is moving at 30 ∘ downward from the horizontal before it is kicked. If all the numerical values are the same as before, find the magnitude of the average force on the ball.
b)Find the direction of the average force on the ball found in Part A.
