Assuming a frictionless track, find the speed of the cart at X (the lowest point). Round off to four decimal places. mass of the cart = 65.9 kg position of the cart = vertically 15.9 m from the lowest point N

A daredevil on a motorcycle leaves the end of a ramp with a speed of 33.2 m/s as in the figure below. If his speed is 31.0 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 daredevil on a motorcyle is at the end of a ramp that is sloped up to the right. An arrow parallel to the ramp's surface is above the daredevil. A dotted-line path traces the trajectory of the daredevil. The path extends up to the right, initially parallel to the surface of the ramp, and decreases in slope until it reaches a maximum, whereupon it extends down to the right with increasing slope magnitude. The vertical distance between the maximum and the highest point of the ramp is h. A horizontal arrow points to the right above the maximum.

A ball is released at a height of h=2.70 m on a frictionless 30.0o slope. At the bottom, it turns smoothly (without loss of speed) onto a 60.0o slope going back up. What maximum height does it reach on the right side?

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 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

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

A student pushes a 0.40 kg box up a 30° inclined plane at a constant speed of 1.2 m/s. The student performs 5.0 J of work and the block moves a distance s along the incline before he stops pushing the box. The frictional force acting on the box is 0.9ON. Determine the value of s.

A 145 kg crate slides down a ramp, starting from rest. The ramp is inclined at an angle of 20.6 degrees with respect to the horizontal and has a height of 1.74 m. The crate is placed on frictionless casters so that it slides down the ramp without friction. What is the final speed of the crate (in m/s) just as it reaches the bottom of the ramp? Use g = 9.81 m/s?.

PRINTER VERSION 1 BACK NEX Z Your answer is partially correct. Try again. In the figure, a frictionless roller coaster car of mass m = 832 kg tops the first hill with speed vo = 19.0 m/s at height h = 44.0 m.

Current Attempt in Progress 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 6.39 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A. B
