The impulse - momentum theorem states that the impulse on an object is equal to:A. The change in its velocityB. The change in its accelerationC. The change in its momentum D. The change in its kinetic energy

Learning Goal: To understand the relationship between force, impulse, and momentum. The effect of a net force EF acting on an object is related both to the force and to the total time the force acts on the object. The physical quantity impulse J is a measure of both these effects. For a constant net force, the impulse is given by J = FAt. The impulse is a vector pointing in the same direction as the force vector. The units of J are N. sor kg · m/s. Recall that when a net force acts on an object, the object will accelerate, causing a change in its velocity. Hence the chiect's momentum in- mail will also change. The Figure F (N) L 12,000 0.0007 1 of 1 t (s) In Parts A, B, C consider the following situation. In a baseball game the batter swings and gets a good solid hit. His swing applies a force of 12,000 N to the ball for a time of 0.70 × 10-³ s. Part A Assuming that this force is constant, what is the magnitude J of the impulse on the ball?

A 0.03 kg ball is thrown horizontally along the (+) x-axis directly towards a wall with a speed of 12 m/s. The ball bounces straight back with a speed of 8 m/s.The impulse of the wall on the ball is: A.) -0.6 kg m/s B.) 1.20 kg m/s C.) -0.2 kg m/s D.) 0.10 kg m/s

complete the following 3 steps. 1. Indicate what your chosen system is (which objects are included in the system?) as well as your initial and final instants. Explain how your choice will help you solve the problem. 2. Draw a momentum-impulse bar chart for your chosen system that is consistent with the information given. 3. Write an equation using the bar chart as a guide and solve for any unknowns. A 6-kg bowling ball moving at 3 m/s hits a single 2-kg pin, knocking it forward at 6 m/s. If the collision took 0.050 s, what average force was exerted on the pin?

A 0.50-kg object travelling at +1.00 m/s collides with a 1.50-kg object that is travelling at -1.00 m/s.    They stick together after the collision. What is the final velocity on the combination? Determine the impulses on each to show they follow Newton’s 3rd law. Determine the change in kinetic energy.

A- Using the equation f=mv/t and the example problem given in the leture answer the following problem. A kick-ball of mass 0.5 kilograms is moving at 4 meters/second after being kicked. The kick lasted 2 seconds. How much force was used to kick the ball?_____newton. B- Ft=mv. impulse = momentum. Due to this formula gymniats practice on thick mats. The mats increase the time that it takes for the gymnast to come to a stop. Thus decreasing the forces acting on the gymnast. (True or False)
