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

5.01

Step-by-step explanation:

You are welcome

Answer 2

0.91 J

Step-by-step explanation:

The kinetic energy of an object is given by

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

where

m is the mass of the object

v is its speed

For the lemming in this problem, when he jumps, we have:

m = 0.0780 kg is the mass

v = 4.84 m/s is the speed

Substituting into the equation, we find:

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