What is a 10.0 G bullet moving at 300m s is fired into? In a police ballistics test, a 10.0-g bullet moving at 300 m/s is fired into a 1.00-kg block at rest. The bullet goes through the block almost instantaneously and emerges with 50.0% of its original speed. What is the average force of […]

What is a 20 g bullet moving at 1000 m s is fired through? A 20g bullet moving at 1000 m/s is fired through a one kg block of wood emerging at a speed of 100m/s. What is the kinetic energy of the block that results from the collision if the block had not been

What is the momentum of a 2000 kg truck that moves at 10 ms? Momentum before the collision is p=mv=2000⋅10=20,000 kgms−1 . When a large truck collides with a small car which undergoes the greater change in momentum? because force and time is same for both the truck as well as car; so the change

Why does the common idea motion implies force make sense to students? Because every object has inertia, which measures how resistant an object is to motion, the idea that the motion of an object implies that there’s a force on the object makes sense to students. O A. Because if there is no force on

Which of the forces acting on the ball is the one that provides the centripetal force? The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal forces. Multiple individual forces can even be involved as long as they add up

What is the associated wavelength of a 0.66 kg ball moving with speed 100 meters per second? λ=hmv=6.6×10−340.66×100=1.0×10−35m. What is the velocity of the 3 kg ball after the collision? The velocity of the 3 kg ball is 4 m/s after the collision. What is the velocity of a 0.06 kg ball moving with 75

What is the final velocity of the car and the truck just after the collision? Final Velocity Formula m 1 v 1 + m 2 v 2 = m 1 v 1 ′ + m 2 v 2 ′ . In a perfectly inelastic collision, the two objects stick together and move as one unit

How do you move a railroad car? Use a locomotive – This a safe way to move railcars because these machines are the heaviest duty for this task. Locomotives are best when moving large number of railcars at a time and they have faster travel speeds. What is the final velocity of the car and

What is the speed of a 1.0 x10 3 kilogram car? A 1.0 × 10³-kilogram car travels at a constant speed of 20 meters per second around a horizontal circular track. Which formulas show the relationships between momentum mass and velocity? p = m v . You can see from the equation that momentum is

What is the speed with which the 3kg object moves to the right? A 3 − k g object moving to the right on a frictionless,horizontal surface with a speed of 2 m / s collides head on and sticks to a 2 − k g object that is initially moving to the left with
