Kicking the ball: Describe the effect of changing the initial conditions (surface gravity, kick angle), and...
Homework Answers
Effect of surface gravity on distance - As the gravity is increased ( while keeping all other things same), the distance covered by the ball will decrease and when gravity is decreased, the distance covered will increase
------------------
Effect of mass on distance - In the absence of air resistance ( ideal condition), mass will have no effects on the distance covered by ball. However, under real conditions, increasing the mass will decrease the distance covered
-------------------
Effect of launch angle on distance - as we increase the angle, distance covered will be less. The maximum range is achieved at 45 degree launch angle.

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...

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...

4 Situation 1: On Earth, you kick a box with a speed of 2 ms? up a smooth ramp that makes a 60° angle with the horizontal. Find the maximum dis- tance the box will travel up the ramp. Then find how long before the box reaches you at the base of the ramp again. 1 Situation 2: Now imagine you are on planet X whose mass is twice that of Earth's but with a radius that is also twice...

6. Someone kicks a ball off of a 15-m-high cliff. The kick is at an angle of 30 degrees above the horizontal with a speed of 20 m/s. In this problem you will be ultimately solving for the distance from the cliff that the ball lands. (a) Write down all the given information. Be sure to organize it effectively. (b) Solve for the time it will take the ball to hit the ground. (c) Solve for the horizontal distance from...
