Q1

Use the foil'owing information to answer question 1 and 2 While a baseball playel catches a baseball, a force F is exerted on the baseball ever time . The baseball has a mass of 1459 and its velocity changed from $50 mfs to + 2.00 rnls due to the force exerted on it by the player. Determine the magnitude of the impulse that the player applied to the baseball. Using the information from question 1,. it the player had applied half the force when she caught the ball, then the interval of time required to - the ball would be Car 1 has a mass of 1.70 x 103 kg and is moving at a constant speed of 10.0 m/s. It strikes Car 2, which is at rest and has a mass of 1.00 x 103 kg. The cars lock together and continue to roll forward. They then collide and lock together with Car 3, which is at rest and has a mass of 1.40 x 103 kg. Before First Collision Car 1 Car 2 Car 3 v = 10.0 m/s V2 = 0 m/s V3 = 0 m/s Immediately After First Collision Car 1 Car 2 Car 3 V 12 Immediately After Second Collision Car 1 Car 2 Car 3 V 123 Note: Vector arrows are not drawn to scale. The maximum speed of this three-car system, v123, immediately after the second collision is m/s. (Record your three-digit answer, do not include units)The diagram below shows a train and car on a collision course. Train locomotive Train track m = 4.7 x 10* kg v = 12.0 m/s N WE S Car m = 2.7 x 10' kg v = 27.0 m/s The momentum of the car -train system immediately before a collision would be Select one: O a. 5.69 x 10* kg-m/s, 7.360 North of east O b. 5.69 x 10 kg-m/s, 82.60 North of east O c. 6.40 x 109 kg-m/s, 7.360 North of east O d. 6.40 x 10 kg-m/s, 82.60 North of eastUse the following information to answer the next question. The following lab set-up consists of two carts on a frictionless surface. Each end of the spring is attached to one of the carts and compressed. The two carts are then held together with a thin wire and are at rest. The mass of Cart A is m and the mass of Cart B is 3.0 m. CART B CART A Wire 3.0 m Spring O After the wire is cut, Cart A moves to the left with a velocity of 1.2 m/s. and Cart B moves to the right with an unknown velocity. CART B CART A Cut Wire VII 3.0 m m Spring O 9000909000090901 Determine the speed of Cart B. O a. 0.40 m/s O b. 2.5 m/s O c. 1.2 m/s O d. 3.6 m/s
