- AsapA stone is thrown horizontally with an initial speed of 10 m/s from the edge of a cliff. If the height of the cliff is 100 m, what is the time of flight of the stone if air resistance is negligibly small?A ball is thrown from the top of a tower at an angle of 40o to the horizontal with an initial speed of 6.60 m/s. During its flight, the only force acting on the ball is the force of gravity. It takes 3.55 s until the ball hits the ground. How tall is the tower?
- A marble is launched from the edge of a table at a angle of 45 ° up from horizontal and goes through the air until it hits the floor. True or False? For such a marble, the magnitude of the acceleration decreases and then increases while it is airborne.You're playing a cartoony racing video game, with a character on a motorcycle. You drive your character off a ledge at 15 m/s. The next ledge for the character's bike to land on is 25 m away (horizontally) and 12 m below. Assume the video game has realistic physics coded into it, except that acceleration due to gravity is only 8.0 m/s^2. a) will your character land on the next platform? b) whether they land or not, find their velocity (magnitude and direction) as they either land on or pass through the 12 m below position.A lowly high diver pushes off horizontally with a speed of 2.88 m/s from the edge of a platform that is 10.0 m above the surface of the water. (a) At what horizontal distance from the edge of the platform is the diver 0.875 s after pushing off? (b) At what vertical distance above the surface of the water is the diver just then? (c) At what horizontal distance from the edge of the platform does the diver strike the water?
- An airplane is moving sideways at a constant pace, and drops two packages. Package #1 is light, while package #2 is heavy. For this problem, ignore air resistance. Package(s) will reach the ground first? Package 1 will land in front of below or behind or beside the plane, and package 2 will land in front of below or behind or beside the plane. Package 1 will land in front of below or behind or beside the other package?Suppose you throw a baseball straight up into the air at t = 0. The ball reaches a maximum height of 22.5 meters above its starting position. Ignore air resistance for this problem. (a) What was the initial velocity of the ball at the moment it left your hand? Hint: the velocity goes to zero at the highest point of the motion. (b) At what time (in seconds) did the ball reach its maximum height? (c) If you threw the ball up into the air with double the initial velocity that you found in part (a), how high would it go?You’ll now apply the horizontal launch to a car accident example. In this scenario, a car driver named Joshua Horton says he was driving at the speed limit of 45 mph when he hit an icy patch and drove through a guard rail of the 15 m tall bridge, before landing 24 m from the base of the bridge. Tes1ng shows that driving through the guard rail lowers a car’s speed by 10 m/s. QUESTION 3: Given the distance that the car landed from the bridge, determine what speed Joshua was actually driving before leaving the bridge. Was he telling the truth or lying?
