Unformatted text preview: B) Momentum of gun? C) Calculate the KE of the bullet after being fired. D) KE of the gun after the gun is fired. A 66kg ice skater moving to the right at 2.58m/s throws a 0.181kg snowball to the right at 36.3m/s. What is the velocity of the ice skater after throwing the snowball? A second skater with a mass of 61.4kg catches it, what is her velocity? A dentists drill starts from rest. After 1.32s of constant angular acceleration it turns at a rate of 31700 rev/min. What is the drills angular acceleration (rad/s2)? Determine the angle through which the drill rotates during this period? A race car accelerates from a speed of 40m/s to a speed of 60m/s in 5 sec., while traveling counterclockwise around a track with a radius of 400m. When the car reaches a speed of 50m/s find. . (a) The magnitude of the cars centripetal accel. (b) the angular speed (c) the tangential accel. (d) the magnitude of the total accerleration....
