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

KE = 54450 J

Step-by-step explanation:

Data:

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

Use the formula:

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

Replace and solve:

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

• 
  `\boxed{\bold{K_(E)=(900\ kg*121(m^(2))/(s^(2)))/(2)}}`

• 
  `\boxed{\bold{K_(E)=(108900\ J)/(2)}}`

• 
  `\boxed{\boxed{\bold{K_(E)=54450\ J}}}`

A kinetic energy of 54450 Newtons is imparted to it.
