Der Vortrag „Momentum: Example“ von Jared Rovny, PhD ist Bestandteil des Kurses „Momentum“.
The momentum of a car traveling in a straight line at 20 m/s is 24,500 kg.m/s. What is the car’s mass?
An 8-kilogram bowling ball bounces off a wall. The initial and final velocity vector of the bowling ball make an angle of θ = 30° with the wall and the initial and final speed of the bowling ball is 10m/s. What is the magnitude of the impulse exerted by the wall on the bowling ball? ( Note: sin(30°) = 1/2 )
A pitcher throws a baseball in a straight line. If the baseballs momentum is 2.1 kg.m/s and its mass is 0.14 kg, what is the speed of the baseball?
An 8-kilogram bowling ball bounces off a wall. The initial and final velocity vector of the bowling ball make an angle of θ = 30° with the wall and the initial and final speed of the bowling ball is 10m/s. What is the magnitude of the average force exerted by the wall on the bowling ball if the collision time is Δt = 0.1 s ? ( Note: sin(30°) = 1/2 )
