I am given the answers just need help with the equations.
3.) a.) A roller coaster is shown below. Determine the velocity of the car at points B and C. (Ans = 16.0 m/s, v = 13.4 m/s) 10.0 mys 12.0 m 4.0 m D.) A uniform rod of length (L=1.00 m, M=50.0 g) is oriented horizontally as shown, it is released and pivots around one end. Determine the angular velocity of the rod at the moment it is oriented vertically. (Hint: the center of mass of the rod falls" a vertical distance % L.) (Ans. 5.42 rad's.) -axis 8.0 m c.) A 2.00 kg mass attached to a spring (k = 100 Nim) sits on a horizontal surface. The mass is pulled 0.400 m toward the night and let go. The coefficient of kinetic friction between the mass and the surface is 0.516. Determine the velocity of the mass when it passes through the equilibrium position. (Ans.y = 1.99 m/s.) w 0.400 m
Rotational Motion & Circular Motion a.) A wheel (R0.200 m) has an initial angular velocity of 12.0 rad/s. It slows down at a constant rate and stops within 4,00 seconds. What is the angular acceleration of the wheel and what is the linear acceleration of a point on the rim? (Ans a-3.00 radis, a-0.600 m/s) 4.) c.) Spike usually weighs 890 N (-200 b). What is his apparent weight at the bottom of the hill (R-150 m)7 (Ans. apparent weight N=1,430 N= 1.61 mg-Spike weighs 1.61 times as heavy as he usually does.) 1: 30.0 m/s c.) Philadelphia Phillies pitcher Cole Hamels throws a baseball (M-145 g. R=26.0 mm) at 45.0 m/s. It rotates at 1,600 rpm. Determine the rotational and translational kinetic energies of the ball. (Ans. K= 147 J, K-59 J.) d.) Tangential acceleration is the rate at which the i.) impulse. i) direction. .) total acceleration v.) speed. changes.
