Vx = (first bold) - (second bold)*(cos(angle))
Vy = 0 - (second bold)*(sin(angle))
Vx^2 + Vy^2 = Vf^2
Take sq rt of Vx^2 + Vy^2... I keep getting .255
Part b
tan(angle) = Vy/Vx
do inverse tan in calculator... this gives u the angle... and it will be pos.
A bicycle has wheels of radius 0.33 m. Each wheel has a rotational inertia of 0.082 kg* m2 about its axle. The total mass of the bicycle including the wheels and the rider is 74 kg. When coasting at constant speed, what fraction of the total kinetic energy of the bicycle (including rider) is the...

A hockey puck moving along the +x axis at 0.5 m/s collides into another puck that is at rest. The pucks have equal mass. The first puck is deflected 37degrees below the +x axis and moves off at 0.36 m/s. Find the speed and direction of the second puck after the...
A 0.015-kg bullet traveling horizontally at 399.9 m/s strikes a 4.1-kg block of wood sitting at the edge of a table. The bullet is lodged into the wood. If the table height is 1.2 m, how far from the table does the block hit the floor?
