define the effect of inertia on how far each can rolls.
A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 5.00 g coins stacked over the 15.0 cm mark, the stick is found to balance at the 42.0cm mark. What is the mass of the meter stick
A point mass of m1 = 2.3 kg is placed at the origin. Masses m2 = 5.4 kg and m3 = 7.6 kg are placed at 3.5 m and -5.8 m on the x-axis, respectively. Find out the location on the x-axis of the center of mass.
First, you will investigate purely vertical motion. The kinematics equation for vertical motion (ignoring air resistance) is given by y(t) = y0 + V0t-(1/2)gt^2 where y0=0 is the initial position, How long does it take for the baseball to hit the gr..
