A 500 kg roller coaster car is on a track. The top of the first hill is 90 m above the ground. After the first hill, there is a loop-the-loop which has its highest point at 50 m above the ground. What is the roller coaster's velocity at the highest point of the loop- the-loop?

Dr. Liu is learning how to juggle. He tosses a tennis ball (probably bad choice since it is so bouncy) up at 2.5 m/s at a height 1.5 m above the floor and attempts to use the other hand to catch the falling ball. The ball hit the floor at his feet. How long was Dr. Liu's tennis ball in the air (between tossing and landing)? Ignore air drag. He should probably practice tossing his juggling ball at the same height and same speed before attempting to juggle. Hint: You can set the final position to be zero.
A basketball is thrown at 45° to the horizontal. The hoop is located 3.6 m away horizontally at a height of 1.2 m above the point of release. What is the required initial speed? m/s
A ball is kicked with an initial horizontal velocity of 16 m/s and initial vertical velocity of 10 m/s. What is the maximum height the ball goes above the ground? Use g = 10 m/s2.
A basketball (a hollow sphere) starts at rest and rolls down a roof. It rolls 4m before leaving the 30 degree roof. a) What is the speed of the ball when it leaves the rooftop? b) If the roof ledge is 5m high, how far away does the ball land from the house? (assume v= 3m/s if you could not solve part a)
A ball is suspended from a light 1.2 m string as shown. The string makes an angle of 27 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1 m/s. PART A. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)? PART B: What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)?
A ball is suspended from a light 1.3 m string . The string makes an angle of 24 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1m/s. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)? What will be the maximum angle, in degrees, the string will make with the vertical?
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.

A paratrooper weighing 180 pounds (including equipment) falls vertically downward from an altitude of 5000 feet and open the parachute after 10 seconds of freefall. Assume that the resistance force of the air is 0.75v when the parachute is closed and 12v when the parachute is open, where the velocity v it is measured in feet / sec. to. a. Find the speed of the skydiver when open the parachute b. find the distance of fall before it opens the parachute. c. What is the limiting velocity vL after it is open the parachute? d. Determine how long the skydiver is in the air after the parachute opens. and. Plot the graph of velocity versus time from the beginning of the fall until the skydiver arrives down
A roof worker loses his grip on his box of tools while working on a tall house. His box slides down the roof. The roof is angled at 29 degrees with the horizontal. The roof is made of a frictionless material. The box travels 5 m down the roof and then leaves the edge of it 12 m above the ground. a). Figure out the box's velocity as it leaves the house's roof? b). How far from the base of the house does the box hit the ground? c). By how much does the box clear the yard fence which is 1.8m tall and located 6.7m away from the base of the house? I TOOLS 5m 29° 12 m 1.8m 6-7m ENGL
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?
It's been a great day of new, frictionless snow. Julie starts at the top of the 60° slope with a push-off velocity of 1.7 m/s as shown in the diagram. At the bottom a circular arc carries her through a 90° turn, and then she launches off a 3.0-m-high ramp. How far horizontally is her touchdown point (in m) from the end of the ramp assuming that air resistance is negligible and that the local acceleration due to gravity is 9.80 m/s2?
