- 1b. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. What are the components of the initial velocity? v0x = ____m/s v0y = ____m/s3. In Physics, the height of a free-falling object at a given time t is given by h = –16t² + v,t + h., where v, is the initial velocity, and h, is the initial height. A student throws a ball upward from a height of 48ft, initially at 32 ft/s. What is the maximum height of the ball?Problem #8
- You are at a circus and you see a stunt man climb up 29.4 meters into a cannon. He gets fired horizontally out of the cannon and lands 140. m away on a trampoline. How long was stunt man in the air for? What was his velocity when he came out of the cannon? m/s What is his horizontal velocity as he hits the trampoline? m/s What is his vertical velocity as he hits the trampoline? m/s What is his speed (velocity magnitude) as he hits the ground? m/s Word Bank: -24 42.2 -36 3.16 2.45 39.8 57.1 24.6 2.03 64.3 1.64 71.2 -18 57.1 61.9 -16While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.61 m/s. The stone subsequently falls to the ground, which is 17.3 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. A) Impact speed: _________________________ m/s B) How much time is the stone in the air? elapsed time: ____________ sFreya clears a crossbar while pole vaulting. She releases the pole before she achieves her peak height. It takes her 2 seconds to fall from her peak height to the landing pit. The landing pit is 1.5 m high. How high above the ground was Freya at the peak height of her vault?
