This is a physics assignment that I missed. Most questions are unrelated to each other so I'd appreciate you doing any question you can and it's parts if it has any.

3 4 delete W S In-Class Assignment - Momentum and Impulse (1) Name: Date: Class: AP Physics BOX IN YOUR FINAL ANSWER WITH CORRECT UNITS. Use g = -10 m/s 1 . With what velocity must a 0.53-kg softball be moving to equal the momentum of a 0.31-kg baseball moving at 21 m/ s? 2. The two quantities needed to calculate an object's momentum are _ and Consider the mass and velocity values of Objects A and B below. Object A Object B Compared to Object B, Object A has _ _ momentum a. two times the b. four times the 2 ko c. eight times the d. the same c. one-half the f. one-fourth the 7= 4m/s v=4m/s g. ... impossible to tell without knowledge of the F and a. 3. Insert these words into the four blanks of the sentence: mass, momentum, acceleration, time, impact, weight, impulse, and force. (Not every npulse word will be used.) In a collision, an object experiences a(n) acting for a certain amount of and which is known as a(n) ; it serves to change the of the object. 4. A tennis ball is at rest when it experiences a forward force to set it in motion. It then strikes a wall where it encounters a force that slows it down and finally turns it around and sends it backwards. I = I = I= Ap = AP=. AP =_ Fapp = 60 N Forall =.

The diagram depicts Before and After vi =5 m/3 vi -5 m/9 velocities of an 800-kg car in two different collisions with a wall. In case A, the car rebounds upon v, = 4 m/3 v -0 m/s collision. In case B, the car hits the wall, crumples up and stops. Assume that the collision time for each collision is the same. In which case does the car experience the greatest momentum change? a. Case A b. Case B c. Both the same d. Insufficient information 7 In which case does the car experience the greatest impulse? a. Case A b. Case B c. Both the same d Insufficient information The impulse encountered by the 500-kg car in case A has a magnitude of _ Nos. a. 0 b. 800 c. 3200 d. 4000 e. 7200 f. Not enough information to determine. 9. Evaluate the potential hazard to a passenger involved A rebound is a special in a head-on collision in which the two cars stick ype of collision involving a direction change - the together compared to when they rebound upon result is a large Av. impact. Explain. 6. A 12 kg rock that is moving at 5.1 m/s in the +x direction experiences a net impulse of 98 N-m in the same direction. What is its final momentum? 7. A player bounces a 0.82-kg soccer ball off her head , changing the velocity of the ball from Vi = (4.8 m/s)x + (-1.3 m/s)y to Vf = (7.2 m/s)x + (4.7 m/s)y. If the ball is in contact with the player's head for .0067s, (A) what is the impulse delivered to the ball with the direction (B) What was the magnitude of the force exerted the ball?fn 8. A 0.15-kg baseball is dropped from rest. If the magnitude of the baseball's momentum is .78 kg m/s just before it lands on the ground, (A) What is the velocity of the ball right before it hits the ground? (B) What height was the ball dropped
