- An object is launched horizontally at a height of 30 m with an initial velocity of 20 m/s. The x-component of the initial velocity is: answer choices 20 m/s 0 m/s 15 m/s not enough informationA 55.0 g Super Ball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 4.50 ms, what is the magnitude of the average acceleration of the ball during this time interval?A man in the back row of 1510 of a theatre wishes to hit a statue in front of the theatre screen with a ball. The statue stands 2 meters tall and the baller is sitting in an elevated seat, 10 meters above the floor the statue stands on. The horizontal distance from the spit baller to the statue is 10 meters. The time of flight of the spit ball is 0.6 seconds given an initial ball speed of 15m/s. Find the velocity of the ball when it is fired.
- A firecracker moves vertically upward and after reaching the highest point in its vertical trajectory, it starts falling down. After it falls down by 17.7 meters in air it cracks into two identical pieces. One of the pieces shoots off horizontally with 11.8 m/s speed. What would be the magnitude of the velocity of the other piece right after they split? Enter your answer in m/s. On your paper, show both your calculation for the magnitude and also the direction of the velocity vector of the second piece. Show your work in detail including your physics- based reasoning.Emily throws a soccer ball out of her dorm window to Allison, who is waiting below to catch it. Emily throws the ball at an angle of 30° below horizontal with a speed of 12 m/s, and Allison catches it 2.5 s later. What is the vertical distance between Emily and Allison, in meters? Use g = 10.0 m/s2.The assignment is to calculate how long it would take for your object to fly from one place to another. The problem is: If I threw a boulder off a 400ft cliff, how long would it take to reach the 200ft cliff below? The velocity is 160ft per second.
- A key falls from a bridge that is 45 m above the water. It falls directly into a model boat, moving with constant velocity that is 12 m from the point of impact when the key is released. What is the speed of the boat? 4 m/s 1 m/s 3 m/s 5 m/s 2 m/sIf a man has thrown a stone of mass 600g straight up 5 m in the air in this case what must be the initial velocity? A 10 m/s B 15 m/s 5 m/s D 7 m/sA person jogs three complete laps around a 200 m track in a total time of 11 minutes. What is the jogger's average velocity in m/s. 0 m/s 3.7 m/s 21.4 m/s 37 0.91
- When an object accelerates at 9.8 m/s2 (or 32 ft/s2), we say it accelerates with 1 g. This is true whether the object is falling under gravity, or due to something else. Using the constant-acceleration approximation, determine how many g's are involved in a football kickoff. The ball is initially at rest on the tee. After being in contact with the kicker’s foot for only 8 ms, it leaves the kicker’s foot at 118 ft/s. Round the final answer to the nearest whole number.A 0.5 kg ball is kicked 5 m/s horizontally from a 20 m high cliff. What is the time of flight?A 0.5 kg ball is kicked 5 m/s horizontally from a 20 m high cliff. What is the range?A catapult lunches a rock at a castle wall. The rock is lunched at a 45 degree angle with a speed of 22 m/s. the castle wall is 45 m away and is 20 m high. Does the rock make it over the wall?
