A roller coster has a loop with 7.62 diameter. a) What is the minimum height above the bottom of the loop required to acheive enough speed so that the coaster does not loose contact with the track? b) How many g's does the passenger expirience at the top of the loop AND at the bottom of the loop upon entering the loop.? c) suppose the coaster came to rest at 3/4 h on the other side of the loop. What fraction of the energy was lost?

A particle, starting from point A in the drawing (the height at A is 3.00 m), is projected down the curved runway. Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 5.02 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A. I

A 800 kg roller coaster goes over the first hill with a speed of 17.0 m/s.  If h = 58 m, determine the change in gravitational potential between A and B.  Use g = 10 N/kg.

A crate with mass m = 33.3 kg being pushed up an incline that makes an angle φ = 22.7 degrees with horizontal. The pushing force is horizontal, with magnitude P, and the coefficient of kinetic friction between the crate and the incline is μ = 0.358. Consider the work done on the crate as it moves a distance d = 5.32 m at constant speed. a. What is work done by the pushing force, in joules?  b. What is the work done by friction, in joules?  c. What is the work done by gravity, in joules?  d. What is the net work, in joules?

A 3.50 kg block is pulled up a frictionless inclined plane by a 60.0 N force that is parallel to the plane, starting from rest.The normal force on the block from the plane has magnitude 15.2 N.What is the block's speed when its displacement up the ramp is 3.40 m? Number i Units

See photo x = 36.0 m, y = 38.2 m, z = 43.2 m a. Assuming the track is frictionless, what is the minimum speed required at Point A for the roller-coaster to reach Point B? b. If the roller-coaster starts at Point A with this speed, how fast will it be going when it reaches Point B? c. What will be the maximum speed of the roller-coaster during this part of its trip?

A spherically symmetric ball of mass m and radius R is centered at the origin. A thin rod has a mass M uniformly distributed along its length L and lies along the x-axis as shown in the figure below. Determine the gravitational potential energy of the system if U = 0 at x = ∞. y L M т

HW 5 3. A playground slide is in the form of an arc of a circle with a maximum height of 2.5 m, with a radius of 8.8 m, and with the ground tangent to the circle. Dr. Ritchey's 16 kg toddler starts from rest at the top of the slide and has a speed of 3.4 m/s at the bottom. a. What is the length of the slide? b.
