Why the change in momentum of the egg as it falls is the same magnitude as the change in momentum it undergoes when it stops? Correct answer: Explanation: In both cases the egg starts with the same velocity, so it has...
What is the change in momentum when a car weighing 700 kg? Answer. The momentum of a car of mass 700kg having initial velocity 100m/s and final velocity 200m/s is 70000kgm/s. What is the kinetic energy of a car of mass...
Which has more momentum a bowling ball or golf ball? A bowling ball has more mass than a golf ball. More mass means more momentum. When a golf ball and a bowling ball are rolling at the same speed the ball...
How do you calculate the force of a bowling ball? To calculate the bowling ball force, multiply the ball mass by the ball velocity squared, then divide by the distance of impact between the ball and pins. What is the momentum...
What is the momentum of a 6.0 kg bowling ball with a velocity? p=6×2.2=13.2kg m/s. Q. How much impulse is needed to stop a 10 kg bowling ball moving at 6m s? Answer and Explanation: Therefore, the impulse needed to stop...
What is the amount of work required to stop a car of 1000 kg moving with? Work required to stop a car is 400000 Joule or 400 kilojoule. To convert km/hr into m/s , we multiply it by 5/18. Here, W...
When a 50000 kg train car moving at 2 m s collides and connects to another identical car initially at rest? A 50,000 kg train car moving at 2 m/s collides and connects to another identical car initially at rest. Find...
What type of force is a car moving? Forces Due to Friction (and Newton’s Third Law) The force of static friction is what pushes your car forward. The engine provides the force to turn the tires which, in turn, pushes backwards...
Why an ice skater is able to increase her angular velocity by folding her arms? When the hands and legs are brought close to the rotational axis, the rotational inertia decreases thereby increasing the skaters angular velocity as per the conservation...
What type of force causes an ice skater to begin to move? At the same time, if there were no friction at all on ice, skating would be impossible, because it is the friction between the skate and the ice when...
