Question

A 10 kg boat is moving 3 m/s. Find kinetic energy.

Answer 1

45J

Step-by-step explanation

kinetic energy can be found through the equation
`K = (mv^2)/(2)`

plug in 10 for m (mass) and 3 for v (velocity)

`K = (mv^2)/(2)\\K = (10*3^2)/(2)\\K = (10*9)/(2)\\K = (90)/(2)\\K = 45 J`

Answer 2

KE = 1/2mv^2
m=10 v=3
KE=1/2*10*3^2
KE= 45 Joules
