1) What is the formula for calculating the amount of energy in an object’s kinetic energy store? Write the units for all of the values as well.
2) An object has a mass of 6 kg and is travelling at 5 m/s. Find the amount of energy in the object’s kinetic energy store.
3) An object has a mass of 800 g and is travelling at 3 m/s. Find the amount of energy in the object’s kinetic energy store.
4) A 1,800 kg car is travelling at 25 m/s. Find the amount of energy in the object’s kinetic energy store. Give your answer in kilojoules.
5) An object is travelling at 6 m/s and it has 72 joules in its kinetic energy store. Find the mass of the object.
6) An object is travelling at 12 m/s and it has 1.8 joules in its kinetic energy store. Find the mass of the object. Give your answer in grams.
7) An object has 417.15 joules in its kinetic energy store and a mass of 10.3 kg. Find the velocity of the object.
8) A scooter has a mass of 120 kg. When the scooter is moving at an unknown speed, it has 21,660 joules in its kinetic energy store. Find the velocity of the scooter.
9) A bullet has a mass of 30 grams. When the bullet is fired out of a gun, the bullet has 9.6 kilojoules of energy in its kinetic energy store. Find the velocity of the bullet.
