The arrow enters the block horizontally at va1 = 35 m/sand passes through to the other side, exiting horizontally at va2 = 15 m/s. a) Determine the speed of the styrofoam after the arrow exits the block. b) Determine where the Styrofoam will land with respect to the arrow. Assume the arrow passedright through the centre of mass of the block, and both objects drop the same vertical distance tothe ground.
Professional baseball pitchers deliver pitches that can reach the blazing speed of 100 mph (miles per hour). A local team has drafted an up-and-coming, left-handed pitcher who can consistently pitch at 41.12 m/s (92.00 mph). Assuming a pitched ball has a mass of 0.1422 kg and has this speed just before a batter makes contact with it, how much kinetic energy does the ball have? Kball= Recall that the acceleration due to gravity is 9.81m/s2. How high would the ball need to be dropped from to attain the same energy as it did when it was pitched (neglect air resistance)? hball=
A heavy ball with a weight of 150 N (m = 15.3 kg) is hung from the ceiling of a lecture hall on a 4.6-m-long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.6 m/s as it passes through the lowest point. What is the tension in the rope at that point?
A 719-N man stands in the middle of a frozen pond of radius 4.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 1.2-kg physics textbook horizontally toward the north shore at a speed of 4.0 m/s. How long does it take him to reach the south shore?
