9, Galileo throws a rock from the top of the Leaning Tower of Pisa at an upward angle of 69.00 with speed vo. The rock is in flight for 5.2 s and hits the ground 15 m from the base of the building. Ignore air resistance and ignore the fact that the two tilts a bit. a) What is the speed vo? Vo b) How high off the ground is the top of the tower? Height of tower c) What...

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 car traveling at 35 mi/h crashes into a tree. The front end of the car compresses and the driver comes to rest after traveling 0.75 m. What was the magnitude of the average acceleration of the driver during the collision? Express your answer in terms of "gs", where 1g 9.80 m/s. Determine the time interval of the collision, in milliseconds. 6. The tower of Pisa is 54.5 m tall. Assuming that Galileo dropped his object from rest from the...

A daredevil on a motorcycle leaves the speed of a ramp with a speed of 33.5 m/s as in the figure below. If his speed is 31.8 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance, m A 44.0-kg projectile is fired at an angle of 30.0 degree above the horizontal with an initial speed of 1 40 times 102 m/s from the top of a cliff...

1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...
