A cat sits on the top of a fence that is 2.0 m high. The cat has a gravitational potential energy of 88.9 J. What is the mass of the cat ?

The mass of the cat is 4.534 kg

Explanation:

Given

gravitational potential energy = 88.9 J

Height h = 2.0 m

To find: mass of the cat

We know that the gravitational potential energy is given by

 = mgh, where

m = mass of body

g = acceleration due to gravity = 9.8 m/

h = height above ground

Hence , mass m =  

                           =

                           = 4.534 kg

Hence the mass of the cat is 4.534 kg

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

it is b. absorbs thermal energy
