Suppose a child drives a bumper car head in into the side rail, which exerts a force of 3,980 N on the car for 0.233 s. What would be the final velocity of the bumper car if its initial velocity was 2.77 m/s and the car plus driver have a mass of 205 kg. You may neglect friction between the car and the floor.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
