Questing 1: A spaceship of mass 2.00 x 106 kg is cruising at a speed of 5.80 x 106 m/s when the antimatter reactor fails, blowing the ship into three pieces. One section, having a mass of 4.70 x 105 kg, is blown straight backward with a speed of 2.20 x 106 m/s. A second piece, with mass 8.50 x 105 kg, continues forward at 1.30 x 106 m/s.
Part A: What is the speed of the third piece?
Part B: What is the direction of the third piece?
Question 2: Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400kg that is traveling horizontally at 11.7m/s. Olaf's mass is 70.2kg.
Part A: If Olaf catches the ball, with what speed nr do Olaf and the ball move afterward?
Part B: If the ball hits Olaf and bounces off his chest horizontally at 7.00m/s in the opposite direction. What is his speed vr after the collision?
Question 3: Two ice skaters, with masses of 40.0kg and 65.0 kg are at the center of a 30.0zn -diameter circular rink. The skaters push off against each other and glide to opposite edges of the rink.
Part A: If the heavier skater reaches the edge in 40.0s. How long does the lighter skater take to reach the edge?
Question 4: A 40.0g ball of day traveling east at 1.50m/s collides and sticks together with a 20.0g ball of day traveling north at 2.50m/s.
Part A: What is the speed of the resulting ball of clay?
Part B: What is the direction of the resulting ball of clay?
Question 5: A 1.8kg object is moving to the right with a speed of 0.80 rn/s when it experiences the force.
Part A: What is the object's speed after the force ends?
Part B: What is the object's direction after the force ends?
Question 6: A tennis player swings her 1000 g racket with a speed of 12.0m/s. She hits a 60 g tennis ball that was approaching her at a speed of 18.0m/s . The ball rebounds at 41.0m/s.
Part A: How fast is her racket moving immediately after the impact? You can ignore the interaction of the racket with her hand for the brief duration of the collision.
Part B: If the tennis ball and racket are in contact for 11.0ms. What is the average force that the racket exerts on the ball?
