Question

A drone moves with kinetic energy of 64.0joules if it weigh 8.0 kg .calculate its velocity​

Answer 1

4 m/s

Step-by-step explanation:

The formula for kinetic energy is
`KE = (1)/(2)mv^2` where m is mass and
`v^2` is velocity squared. This problem can be solved by rearranging this formula to solve for velocity.

Step 1: Isolate the velocity

`2KE=mv^2`

`(2KE)/(m)=v^2`

`v=\sqrt{(2KE)/(m)}`

Step 2: Plug in given numbers and solve

`v=\sqrt{(2*64)/(8)}=√(16)`

v = 4 m/s
