Homework Statement
A car starts from rest and accelerates around a flat curve of radius R = 31.7 m. The tangential component of the car’s acceleration remains constant at at = 2.97 m/s2, while the centripetal acceleration increases to keep the car on the curve as long as possible. The...
The problem was much easier than thought. Find velocity of the first object from kinetic energy. Use this velocity times the cosine of the angle. Use that velocity for finding the new kinetic energy. Giving an answer of 0.728J.
Figured it out thank you, found velocity of basketball after first collision, which is the same as before, and then velocity of the golf ball after hitting the basketball. Momentum of the golf ball was 0.557 kg*m/s, and height after being hit is 7.737m
Homework Statement
After several large firecrackers have been inserted into its holes, a bowling ball is projected into the air using a homemade launcher and explodes in midair. During the launch, the 5.43-kg ball is shot into the air with an initial speed of 12.9 m/s at a 39.9° angle; it...
Homework Statement
Place a golf ball on top of a basketball, and drop the pair from rest so they fall to the ground.The golf ball stays on top of the basketball until the basketball hits the floor. The mass of the golf ball is 0.0459 kg, and the mass of the basketball is 0.587 kg.
a) If the...
Homework Statement
A ball with mass m = 0.230 kg and kinetic energy K1 = 1.16 J collides elastically with a second ball of thesame mass that is initially at rest. After the collision, the first ball moves away at an angle of θ1= 37.6° with respect to the horizontal. What is the kinetic energy...
