Question

A 0.0780 kg lemming runs off a 5.36 m high cliff at 4.84 m/s. what is its kinetic energy(KE) when it jumps PLEASE HELP ME

Answer 1

0.91 J

Step-by-step explanation:

Answer 2

0.91 J

Step-by-step explanation:

Kinetic energy is given by:

`K=(1)/(2)mv^2`

where

m is the mass

v is the speed

For the lemming in this problem, when it jumps from the cliff, we have

m = 0.0780 kg

v = 4.84 m/s

Substituting into the equation,

`K=(1)/(2)(0.0780)(4.84)^2=0.91 J`
