7. You can swing a ball on a string in a vertical circle if you swing it fast enough. Butif you swing too slowly, the string goes slack as the ball nears the top. Explain whythere's a minimum speed to keep the ball moving in a circle.8. A curve in a road has a bank angle calculated and posted for 80 km/h. However, theroad is covered with ice, so you cautiously plan to drive slower than this limit. Whatmight happen to your car? Why?9. Why do airplanes bank when they turn? How would you compute the banking anglegiven the airspeed and radius of the turn? [Hint: Assume an aerodynamic "lift" forceacts perpendicular to the wings].

We are suppose to solve only one question. Please post other question as a separate question.

You have been chosen as the test subject for the newest attraction at Canada’s Wonderland. This attraction is a single-person roller coaster ride that has a 25.0 m drop followed by a collision with a plunger attached to a large spring that brings the ride to rest. The plunger/spring mechanism is composed of a large spring with a mass of 62.5 kg made of pure iron..The cart has a mass of 75.0 kg and starts at rest from the top of the track. To determine the total mass of the cart during the ride you must add your mass to the system. As the cart moves down the track it has been determined that friction in the wheels and axles results in the production of 12750 J of thermal and sound energy combined. The plunger/piston at the bottom of the device has been designed to stop the cart with a maximum acceleration of 5.00 g’s (i.e. 49.0 m/s2). What is your approximate mass in kilograms? MY MASS IS 82 kg Problem 1: The cart with you inside of it starts from rest at the top of the ride.…

Q5. the acceleration due the gravity on the moon is 1/6" of what it is on earth. If you can throw a baseball on earth to reach a maximum height of 20m, how high could you throw a baseball on the moon? If you caught it when it came back down, how much time would elapse between your throw and catch? 3.-0 18m V-18.8m * Figure (1)
5. A simple pendulum at the UCR department of physics and astronomy has a length of 20 m, and the acceleration due to gravity at this location is measured to be 9.803 m/s². Calculate the period of the pendulum.
Body U with mass 5m is stacked on the top body W with mass m, and released. The bodies are in contact along the frictionless interface at 45° to the vertical. The body U is in contact with the frictionless vertical wall. Body W lies on the floor with coefficient of friction u. Relevant dimensions are shown in the figure. Express the results in terms of given quantities: m, g, h and µ (except when µ is given numerically). You need not evaluate sin 45° = cos 45° = 2/2. h U: 5m C 45 D W: m 3h
3) The ME Department just purchased a new mega-drone that weighs 220 lbs and can descend autonomously to land on its own. The drone company included the graph shown below for how much force is applied to the Thrust 'T'. If the operator allows the autonomous descent when the drone has an initial downward velocity of 2 ft/s, calculate the velocity of the drone after 3 seconds.

A 10 lb weight is tied at the end of a rope 2 ft long and is swung in a vertical circle in a clockwise direction. If the maximum tension on the string is limited to 100 lbs, compute the maximum velocity that the weight will be swung, the velocity at the top, and the tension on the string at the top.
7. A ball attached to a string of length 0.25 meters is whirled around in a circular path. It experiences a centripetal acceleration of 40 m/s². a. What is the tangential velocity of the ball? b. How long does the ball take to make one complete revolution?
QUESTION TWO: A car is capable of reaching 27 km/h from rest in 4 seconds on a level road against resistances amounting to 4% of the vehicle mass. If the car has a mass of 1200 kg, calculate the minimum distance over which it could reach 36km/h from rest if towing a caravan of mass 700 kg. Assume the tractive effort to be constant and the tractive resistance to be the same rate for car and caravan.
