Galileo's assistant drops a cannonball from the top of the Leaning Tower ofPisa. The ball falls from rest in a straight, vertical line under the influence ofgravity alone until it hits the ground. It takes 3.37s to hit the ground.Take the magnitude of the acceleration due to gravity to be g = 9.8 ms 2.Give numerical answers to two significant figures.(a) Calculate the height of the Leaning Tower, and the final speed that theball reaches before hitting the ground.(b) Draw a graph of the velocity v (in metres per second) of the ball againstthe time t (in seconds), from the time at which the ball is dropped untilthe instant before it hits the ground.

A thoughtful person on a bridge reflecting on his awesome Physics class sees a small stone by his feet. Hmm, he thought to himself. Using his foot he slowly nudged the stone off the surface of the bridge and using his cell phone he timed how long it took to hit the water, about 1.75 s. How high (m) is the bridge above the water? (neglect air resistance)
A jet plane comes in for a landing with a speed of 120 m/s. The length of the runway is 500 m. From the instant the plane touches the runway, what is the magnitude of the acceleration needed to stop within the runway? Write your answer in terms of m/s2.
A bb is shot downward from the top of a building leaving the barrel with an initial speed of 90.3 m/s downward. The top of the building is 60.1 m above the ground. How much time elapses between the instant it leaves the barrel and the instant of impact with the ground? Round your answer to 3 decimal places.
A missile silo is used to launch military rockets vertically upward out of the silo, giving the rocket an initial speed of 79.6 m/s at ground level. As the rocket clears the silo, the engines fire, and the rocket accelerates upward at 3.90 m/s2 until it reaches an altitude of 1,080 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s². (You will need to consider the motion while the engine is operating and the free-fall motion separately. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Determine the velocity of the rocket (in m/s) at the end of the engine burn time and also the burn time (in s). (For the velocity, indicate the direction with the sign of your answer.) velocity at end of engine V = 92.22 Check your kinematic equation relating vo, V1, ay, and AYo → 1 (where velocity of rocket as it clears the silo, v, = velocity of the rocket at…
The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 2.15 m above the floor. The ball hits the floor 0.265 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 61.2 m/s^2 30.6 m/s^2 45.9 m/s^2 97.9 m/s^2
NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec. Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.
A boat crosses a 222 m wide river flowing at 4.8 m/s to reach a dock directly on the other side. If the boat motor can propel the boat at 14 m/s across the water, how long (in seconds) will it take the boat to reach the dock assuming it travels in a straight line)?
A hot air balloon is moving vertically upwards at a constant rate of 9.0 m/s. As the balloon rises, a package is dropped from the balloon and it takes 5 s to hit the ground. How far did the package fall? Make sure to include a diagram of the physical situation, label known and unknown quantities with units, and coordinate system. Thanks!
An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +23.3m/a and measures a time of 24.4s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? (Positive=up, negative =down)
