- To celebrate the start of October, you want to win a pumpkincatapult contest, which requires you to build a catapult and launcha pumpkin from it. You build your catapult so that it releases thepumpkin when the catapult arm is exactly vertical, as shown inthe picture. a.Draw a picture and make a list of known and unknownquantities for the scenario b.Suppose the catapult arm has a length of R = 3 m and the pumpkin undergoes uniform circular motion with an acceleration of a = 75 m/s^2 before it is launched. What is the speed of the pumpkin at the moment it is launched?1 A skateboarder is trying to skate horizontally off a building and jump over a pool as shown! The pool is 10.0m wide and the roof of the building is 12.0m above where he will land. Neglect drag. How long will the skateboarder remain in the air? 2 S With what initial speed (in given units) does the skateboarder need to barely clear the pool? 14 mph Would the skateboarder clear the pool if he skated off the building with an initial speed of 18mph? yesA smart ball, with a speedometer, is kicked with an initial speed of 37.0 m/s, then follows a projectile trajectory as shown. The speedometer recorded that the ball's lowest speed along its trajectory (at the highest point) is 28.0 m/s. What is the ball's initial launch angle measured in degrees? Origin y L
