Question

Usami Bolt has a mass of 85kg and is running at a steady speed of 10m/s how much kinetic energy does he have

Answer 1

Ek = 4250 J

Step-by-step explanation:

Data:

• m = 85 kg
• v = 10 m/s
• Ek = ?

Formula:

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

Replace and solve:

• 
  `\boxed{\bold{Ek=(85\ kg*(10(m)/(s))^(2))/(2)}}`

• 
  `\boxed{\bold{Ek=(85\ kg*100(m^(2))/(s^(2)))/(2)}}`

• 
  `\boxed{\bold{Ek=(8500\ J)/(2)}}`

• 
  `\boxed{\boxed{\bold{Ek=4250\ J}}}`

It has 4250 Joules of Kinetic Energy.
