Another stone is thrown at an angle of 45° below the horizontal exactly 1 (one) second after the first with some initial velocity. As it turns out the two stones hit the water at exactly the same moment. (Hint: after means shorter time.) a) (20 pts) What is the initial velocity of the second stone? b)...

Question 2 1 pts Kirk, Spock, and McCoy stand on the top deck of a parking garage on planet Earth, 19 m above the ground below. For reasons that are unknown to us, they simultaneously throw pebbles off the deck, each at the same speed of 15 m/s. Kirk throws his up at an angle of 45 degrees above the horizontal, Spock throws his perfectly horizontally, and McCoy, in a fit of pique, throws his straight down toward the ground....

Six baseball throws are shown below. In each case, the ball is thrown with speed v at an angle θ from the horizontal
Projectile Motion Ranking TaskSix baseball throws are shown below. In each case, the ball is thrown with speed v at an angle θ from the horizontal. In all cases, the baseball is thrown from the same height H above the ground. Assume for the basis of these rankings that the effects of air resistance are negligible.Part ARank these throws based on the maximum height reached by the ball.Rank from largest to smallest. To rank items as equivalent, overlap them.Part BThis...

Answer: 10.12 A key is dropped from a bridge that is 40.0 m bove the water. At the moment the key is released a model boat is 10.5 m away from the bridge and moving towards the bridge with constant velocity. If the key falls directly into the model boat, calculate the Velocity of the boat. Answer: 11. [2pt] Arie is aimed honuntaily a target located 345 m away.

An 80.0 kg bungee jumper drops from rest off a bridge that is 200.0 m above a river. As he falls, air resistance is negligible, and the unstretched bungee cord attached to him uncoils. The mass of the bungee cord is negligible. When the jumper is 50.0 m below the bridge, the bungee cord is completely uncoiled and forms a straight line. Below that point, the bungee cord acts as a spring, obeying Hooke's law as it is stretched beyond...

When bungee jumping from a high bridge over Victoria Falls, an operator first attaches an elastic rope to the jumper. The jumper then jumps off the bridge, falling freely until they reach the unstretched length of the rope Then, the rope begins to stretch and slows the jumper to a stop. The rope pulls the jumper back up, and they oscillate up and down for a while until the operator pulls the jumper back up to the bridge. The rope...
