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 3.0 times 10^-3 s. The force exerted on the ball by the foot is given by F(f) = [(6.0x10^6)/-(2.0x10^9)t^2]N for - lessthanorequalto t lessthanorequalto 3.0x10^-3s. Find the magnitude of the impulse delivered to the ball. Find the magnitude of the average force exerted on the ball by the player's foot. Find the magnitude of...
10.7 A soccer player deflects a soccer ball by kicking it. Initially the soccer ball (mass 0.40 kg) is moving horizontally to the left witha speed of 20.0 m/s. The kick causes it to have an initial, post-kick velocity of 30.0 m/s with an angle of 45 upward and to the right. If the time that the player's foot is in contact with the soccer ball is 0.010 seconds find: A. The impulse of the net force The average net...
10) A soccer player hits a 0.20 kg ball which is incoming with a speed 5 m/s. After the kick, the ball change direction and start going in the opposite direction with 4 m/s. What is the average force exerted by the the impact time is 0.02 seconds? a. 90 N b. 50 N c. 40 N d. 10 N e.0N
While playing volleyball, a player sees the ball coming toward them with a velocity of 10 m/s. They hit the ball, and the ball rebounds at an angle of 30owith a velocity of 15 m/s. Find the impulse and find the average force applied to the ball during impact if the mass of the ball is 1 kg and the time of the impulse was 2 ms.
A bat hits a ball of 0.145 kg. Initially, the ball travels to the right at 50 m/s, and after being hit it travels to the left at 30 degree respect to the horizontal and a speed of 65 m/s. Find the impulse applied to the ball The average force acting on the ball while it was in contact with the bat for 1.75 ms
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...
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 1.10 x 10 s, and the force of the kick is given by F(t) = [(8.13 x 105) - (7.39 X 10821 N for Osts 1.10 X 10 TS wheret is in seconds. Find the magnitudes of the following: (a) the impulse on the ball due to the kick, (b) the average force on...
9. A player bounces a 0.48-kg soccer ball off her head, changing the velocity of the ball from vi (8.9 m/s)i+ (-2.8 m/s )j to v (5.1 m/s)i+ (3.8 m/s )j. a. If the ball is in contact with the players head for 6.7 ms, what is the direction of the impulse delivered to the ball? b. What is the magnitude of the impulse delivered to the ball? c. Find the magnitude and direction of the force if the time...
A soccer ball player bounces the ball off her head, changing the velocity of the ball. She changes the x component of the velocity of the ball from vix = 9.5 m/s to vfx = 4.7 m/s and the y component from viy = −3.3 m/s to vfy = 3.2 m/s. If the ball has a mass of 0.44 kg and is in contact with the player's head for 7.1 ms, determine the following.(a) direction of the impulse delivered to...
A soccer ball player bounces the ball off her head, changing the velocity of the ball. She changes the x component of the velocity of the ball from vix = 8.4 m/s to vfx = 5.6 m/sand the y component from viy = −3.5 m/s to vfy = 3.7 m/s. If the ball has a mass of 0.44 kg and is in contact with the player's head for 7.1 ms, determine the following (a) direction of the impulse delivered to...
