Asoccer player kicks a soccer ball of mass 0.40 kg that is initially at rest. the player's foot is in contact with the ball for 2.2 multiplied by 10-3 s. the force of the kick is given by the following formula for 0 t 2.2 multiplied by 10-3 s, where t is in seconds. f(t) = [(7.4 multiplied by 106)t - (2.8 multiplied by 109)t2] n (a) find the magnitude of the impulse imparted to the ball. incorrect: your answer is incorrect. n

I = 7.96Ns

Explanation:

We need to integrate the expression f the force F, so:

Solving the integral:

 Evaluating the expression:

I = 7.96Ns

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
