1. A soccer player can kick a ball with maximum initial speed 10 m/s. She kicked the ball at different angles to check how the horizontal distance to the point the ball hits the ground changes with the angle the ball is kicked. Calculate the horizontal distance for different angles and draw a graph of the horizontal distance versus the angle θ with the ground. What is the angle at which the distance is maximum? Can you explain why there...
Problem 3: You kick a soccer ball of mass m initially on the ground with a speed v at an angle 0 above the horizontal direction (see Fig.1). Key Concepts: Impulse-Momentum Theorem, 2D kinematics, Conservation of Energy a) What is the average force you had to apply if, during the kick, you make contact with the ball for At seconds? b) What is the maximum height the ball reaches? hmax FIG. 1
You kick a soccer ball straight upwards into the air. Your friend times the ball and it takes a total of 3.31 seconds for the ball to go up, come down, and return to the point where you first kicked it. What was the ball's initial velocity (in m/s) immediately after the kick? (Use g = -9.8 m/s2 and round to 3 significant figures) I believe it's 16.2 m/s?? Not sure if I'm right though.
Can a goalie kick a soccer ball without the ball bouncing on the ground and score (not in their own net)? The distance for a soccer field is 100 meters long and goalies can kick the ball with a speed of 30 m/s. (Neglect air resistance). What is the max distance they can kick?
A soccer ball of mass 0.36 kg is rolling with velocity <0, 0, 1.5> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.7 N.s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.34 N in the direction opposite to the direction of the ball's time 1.5 s after you kick it, assuming that the ball is at the origin at the moment it is kicked....
A soccer ball of mass 0.39 kg is rolling with velocity <0, 0, 2.4> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.4 N·s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.32 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s after you...
A soccer ball of mass 0.50 kg is rolling with velocity 0, 0, 1.8 m/s, when you kick it. Your kick delivers an impulse of magnitude 1.2 N · s in the −x direction. The net force on the rolling ball, due to the air and the grass, is 0.22 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s...
A soccer player can kick the ball 23 m on level ground, with its initial velocity at 36 ∘ to the horizontal. a.At the same initial speed and angle to the horizontal, what horizontal distance can the player kick the ball on a 20 ∘ upward slop
Determine the initial velocity with which a soccer player must kick the ball, such that the ball bounces and then achieves maximum height of 2.20 m at pt. C or just passing under the horizontal bar. Coefficient of restitution between the ball and the field is e=0.5 .
A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 1.40 x 103 s, and the force of the kick is given by F(t) = [(7.20 x 105)t - (5.14 x 108)+21 N for Osts 1.40 X 10's, where t is in seconds. Find the magnitudes of the following: (a) the impulse on the ball due to the kick, (b) the average force on...
