Show that for a projectile d2 (v2) / dt2 = 2g2

A car's momentum is p when it is traveling with a velocity of v. If the velocity of that car doubles, what is the new momentum of the car? 1/2p p 2p 4p

A cart is rolling across the floor at a constant velocity of 2 m/s to the right. The cart is pushed again to the right, and it starts to accelerate. How are the force of the push and acceleration of the cart related?

Calculate the total mass of these letters in grams (mxe=131.29amu)

What is the process when thermal energy is being added

a bike is moving with a velocity of 90km/hr. after applying break it stops in 5 sec. calculate the force applied by brakes. mass of motercycle and rides is 200 kg

V=345m/s, 7210Hz, X=?

As a mercury atom absorbs a photon of energy, an electron in the atom changes from energy level d to energy level e. Determine the energy of the absorbed photon in electronvolts.

During an exothermic reaction, the energy given off comes from atoms being consumed mass being burned into energy the breaking and forming of bonds mass being created

Can electrostatic attract both pull and pull?

Ways that charges can be transferred
