8) Calculate the kinetic energy of a truck that has a mass of 6100 kg and is moving at 55 m/s.

Explanation:

The kinetic energy of an object can be found by using the formula

v is the velocity

m is the mass

From the question we have

We have the final answer as

Hope this helps you

scientific laws are the result of testing theories and proving them to be facts.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
