Which formula is used to find fluctuation of the shape of body

A man pushes a sled across the snow, using a force of 300 N over a distance of 2 m. What is the kinetic energy of the sled after he pushes it? Assume there is no friction.

Slow pain originating from an internal organ is often perceived as coming from an area of the body totally unrelated to the source. this is known as

A proton, mass 1.67 * 10-27 kg and charge + 1.6 * 10-19 c, moves in a circular orbit perpendicular to a uniform magnetic field of 0.90 t. find the time for the proton to make one complete circular orbit.

Which statement is true about using shorter, steeper inclined planes to lift an object?

A projectile (mass = 0.226 kg) is fired at and embeds itself in a target (mass = 2.04 kg). (the target is initially stationary). the target (with the projectile in it) flies off after being struck.

Which energy transformation takes place when a firecracker explodes

Newton's first law states that an object traveling with a constant velocity will remain traveling at a constant velocity unless an unbalanced force acts.

A karate expert breaks a stack of bricks with his bare hand. If the force applied is 520 newtons and the impact time is 5.0 * 10-4 seconds, what is the value of impulse?
