The diagram shows a cart at four positions as it moves along its track. At which position is the sum of the potential energy and kinetic energy of the cart the same? B Ⓒ A B at A and C all positions, A through D at Rand D

Consider the given pulley system. The rope is drawn towards the motor with a speed of 3 m/s. What is the speed of mass A and in what direction is it moving?

V₂ - V₁ = 2 V₂ - V₁ = 1 3 P A modern art sculpture consists of a collar, a spring, and a circular track. The collar has a mass of m = 6 kg and the radius of the track is r = 1 m. If the spring is attached to a point P which is a vertical distance d = 0.3 m away from the perimeter of the circular track (d is measured between point 1 and point P), determine the change in potential energy between state 1 and state 2, and between state 1 and state 3. N The unstretched length of the spring is 0.15 m and the spring constant is k = 85- m UBC Engineering

The pinion (gear 2 on shaft a) rotates at 635 rev/min clockwise and transmits 1305 W through the idler pair (gears 3 and 4 on shaft b) to the output gear (gear 5 on shaft c). Gears 2 and 3 have a module of 2 mm, and gears 4 and 5 have a module of 3 mm. Pressure angles are all 20 degrees. Solve for the magnitude of the force that shaft b must apply to gears 3 and 4 to maintain static equilibrium in the figure shown here. The figure is not to scale.
