calculate the kinetic energy of a 210g softball travelling at 35 m/s
Answer:
To calculate the kinetic energy of an object, you can use the formula:
\text{Kinetic Energy} = \frac{1}{2} \times \text{mass} \times \text{velocity}^2
Given:
- Mass of the softball = 210g = 0.21 kg (since 1 kg = 1000g)
- Velocity of the softball = 35 m/s
Plugging in the values:
\text{Kinetic Energy} = \frac{1}{2} \times 0.21 \, \text{kg} \times (35 \, \text{m/s})^2
\text{Kinetic Energy} = \frac{1}{2} \times 0.21 \times 1225
\text{Kinetic Energy} = 0.5 \times 0.21 \times 1225
\text{Kinetic Energy} = 0.105 \times 1225
\text{Kinetic Energy} = 128.625 \text{ joules}
Therefore, the kinetic energy of a 210g softball traveling at 35 m/s is 128.625 joules.
