The kinetic energy of an object can be calculated using the formula KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity.
1. KE = 1/2 * 0.01 kg * (1 m/s)^2 = 0.005 Joules
2. KE = 1/2 * 0.1 kg * (15 m/s)^2 = 11.25 Joules
3. KE = 1/2 * 0.1 kg * (10 m/s)^2 = 5 Joules
4. KE = 1/2 * 0.01 kg * (2 m/s)^2 = 0.02 Joules
Therefore, option 1, 10 grams of water falling at 1 m/s, will result in the least kinetic energy when it collides with the ground.
Which falling object will result in the least kinetic energy when it collides with the ground?
1. 10 grams of water falling at 1 m/s
2. 100 grams of dirt falling at 15 m/s
3. 100 grams of water falling at 10 m/s
4. 10 grams of dirt falling at 2 m/s
