A 0.25 kg Soccer ball is rolling at 6,0 m/s toward a player, The player kicks the ball in the opposite direction and gives it a Velocity of 24.0 m/s. A) What is the change in Momentum of the Ball? B) If the actual kick lasts ,02 selonds, what Force acts on the ball?

A) ΔP = 4.5 [kg*m/s]

B) F = 375 [N]

Explanation:

The linear momentum is defined as the product of the mass of a body by Velocity, therefore we must calculate the momentum for each case.

where:

P = linear momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

A)

When the soccer ball is rolling towards the player

After kicking the ball

Therefore the change  momentum is equal to

ΔP = 6 - 1.5 = 4.5 [kg*m/s]

B) Momentum is defined as the force applied for a certain time, this momentum produces a linear momentum.

We must be especially careful in the directions of the movement, since depending on the direction a positive or negative sign must be included according to the established convention. In this particular case we are going to take the kick and the direction of this as positive, that is to say, the ball moves in the negative direction and after hitting the ball it moves in a positive direction.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
