Question

An artificial satellite of mass 900kg Is launched at a speed of 11,000 m/s from its launching station. How much is the kinetic energy imparted to it?

Answer 1

Answer:

KE = 54450 J

Explanation:

Data:

• m = 900 kg
• v = 11.000 m/s
• KE = ?

Use the formula:

• $\boxed{\bold{K_{E}=\frac{m*(v)^{2}}{2}}}$

Replace and solve:

• $\boxed{\bold{K_{E}=\frac{900\ kg*(11.000\frac{m}{s})^{2}}{2}}}$

• $\boxed{\bold{K_{E}=\frac{900\ kg*121\frac{m^{2}}{s^{2}}}{2}}}$

• $\boxed{\bold{K_{E}=\frac{108900\ J}{2}}}$

• $\boxed{\boxed{\bold{K_{E}=54450\ J}}}$

A kinetic energy of 54450 Newtons is imparted to it.
