6. The tower of Pisa is 54.5 m tall. Assuming that Galileo dropped his object from rest from the top of the tower and that the effects of air resistance were negligible, how long would it take the object to fall, in seconds? What is the velocity of the object when it hits the ground? 7. A ball is thrown directly downward with an initial speed of 9.50 m/s from a height of 30.0 m. After what time interval does...

A pair of glasses are dropped from the top of a 32.0 m high stadium
A pair of glasses are dropped from the top of a 32.0 m high stadium. A pen is dropped from the same position 2.00 s later. How long does it take for the glasses to hit the ground? How high above the ground is the pen when the glasses hit the ground? (Disregard air resistance)

A rock is dropped from the top of a vertical cliff and takes 3.00 s to reach the ground below the cliff. A secon rock is thrown vertically from the cliff, and it takes this rock 2.00 s to reach the ground below the cliff from the time it is released. With what velocity was the second rock thrown, assuming no air resistance? Select one: a. 5.51 m/s downward , b. 4.76 m/s downward X O c. 12.3 m/s downward...

A 5.00-kg watermelon is dropped from rest from the roof of a 20.0-m -tall building and feels no appreciable air resistance. Part A) Calculate the work done by gravity on the watermelon during its displacement from the roof to the ground. Part B) Just before it strikes the ground, what is the watermelon's kinetic energy? Part C) Just before it strikes the ground, what is the watermelon's speed? Part D) Would the answer in part A be different if there...

A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...

A question from lecture: can/would a penny dropped from the top of the Empire State Building kill a pedestrian at ground level? This a very old and question that has persisted in American culture for generations since the thrill of the days the this building reigned as the world’s tallest. But let’s play physicist and reduce the problem to evaluate the potential outcome and assume that you could drop a penny from the height of the Observation Deck on the...
