A kid of mass m=26 kilogram slides down a slide of height h=2.9 meter without friction. Let gravitational potential energy be zero at ground level.
m= 26 kilogram
h= 2.9 meter
a) Write an expression for the kid total mechanical energy E, at the top of the slide.
b) Find the change in the kid potential energy delta U in joules from the top to the bottom of the slide.
c) Determine the kid final speed?
A 75 g, 31 cm long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 12 g ball of clay travelling horizontally at 2.1 m/s hits and sticks to a very bottom tip of the rod.
A point charge (m = 1.0 g) at the end of an insulating string of length 53 cm (Fig. 16-66) is observed to be in equilibrium in a uniform horizontal electric field of E = 9500 N/C, when the pendulum's position is as shown in Fig. 16-66, with the charg..
