In summary, the problem involves finding the average force exerted on a .45-kg ball by a soccer player during a kick that results in the ball reaching a maximum height of 2 m and traveling a horizontal distance of 5 m in a duration of .04 s. The solution requires finding the horizontal and vertical components of the initial velocity, which can be done by solving for the magnitude of the velocity using the impulse equation and then using trigonometric functions to find the components. Neglecting aero drag, the average force can be calculated as the final velocity divided by the duration of the kick.

Homework Statement


Soccer player kicks stationary .45-kg ball to a teammate. The balls reaches a max height above ground of 2m at a horizontal distance 5m from the point where it was kicked. The duration of the kick was .04s. Neglecting aero drag, determine the magnitude of the average force the player exerted on the ball.

Homework Equations


Impulse = Favg (Delta T)

The Attempt at a Solution


I know how to solve the problem I just don't know how to get the components of velocity Vsuby and Vsubx. Just need help with that part, you'd solve for both velocities find the magnitude of the velocity, use the impulse equation plug and have Favg = mvf / Delta T.

Related to Find Force Exerted on Soccer Ball, Impulse Q Homework

1. What is the formula for calculating the force exerted on a soccer ball?

The formula for calculating the force exerted on a soccer ball is F = m * Δv / Δt, where F is the force, m is the mass of the ball, Δv is the change in velocity, and Δt is the time over which the change in velocity occurred.

2. How is impulse related to force and momentum?

Impulse, denoted as Q, is the change in momentum of an object. It is directly proportional to both force and time, meaning that a greater force or a longer amount of time will result in a larger impulse. This is represented by the equation Q = F * Δt = m * Δv.

3. What factors affect the force exerted on a soccer ball?

The force exerted on a soccer ball is affected by several factors, including the mass of the ball, the velocity at which it is kicked, and the duration of the kick. Additionally, external forces such as air resistance and friction can also impact the force exerted on the ball.

4. How does the force exerted on a soccer ball change when it collides with another object?

When a soccer ball collides with another object, the force exerted on the ball changes due to the impulse of the collision. The change in velocity and the duration of the collision will determine the magnitude of the force exerted on the ball.

5. Can the force exerted on a soccer ball be negative?

Yes, the force exerted on a soccer ball can be negative if the ball is decelerating. This can happen, for example, when the ball is kicked with a certain velocity and then slows down due to air resistance. In this case, the change in velocity would be negative, resulting in a negative force exerted on the ball.
