To find the velocity, you can use the equation for kinetic energy: KE = 0.5 * mass * velocity^2. Rearranging the equation gives 45 = 0.5 * 30 * velocity^2. Solving for velocity gives velocity = √(2 * 45 / 30) = √3 = approximately 1.73 m/s.
Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules

30kg = 30kg.
3 tenths of 30kg = 3/10 * 30kg = 9kg
If an object has a mass of 30 kg, its mass on Earth would also be 30 kg. Mass is a measure of the amount of matter in an object, and it remains the same regardless of the gravitational force acting on it.
To find out how many fifths are in 30kg, you first need to determine the value of one fifth of 30kg. One fifth of 30kg is calculated by dividing 30 by 5, which equals 6kg. Therefore, there are 6kg in one fifth of 30kg.
30kg is equal to approximately 66 pounds.
20% of 30kg= 20% * 30= 0.2 * 30= 6kg
The planet with the least gravitational potential energy when a 30kg bowling ball is lifted to a height of 1m would be the planet with the lowest surface gravity. As an approximation, if we consider only the eight planets in our solar system, Mercury has the lowest surface gravity, followed by Mars. So, if you were to drop a 30kg bowling ball from a height of 1m on either Mercury or Mars, it would have the least gravitational potential energy relative to the other planets.
The answer is 30kg
The momentum is given by the formula... p=mv p=momentum m=mass v=velocity In your question your mass is 30kg and your velocity is 10m/s just do simple math and your momentum is 300kg*m/s
