You are planning a deep space exploration and want to take your cat with you. If your spacecraft achieves a maximum speed of 87% of the speed of light, how much additional energy is required to bring your cat (during the acceleration only)? Express this quantity in units of Petajoules (1015).Assume you start from zero velocity and your magical cat does not require additional food or litter. The cat weighs 8.5 lbf. Use LaTeX: 3\times10^8 3 × 10 8 m/s for the speed of light.

E = 1.7 10² PJ

Explanation:

Let's use the special relativity relations, specifically the energy of a body is

           E = γ mc²

           γ =

where m is the rest mass

for that case they tell us that the speed of the body is 87% of the speed of light

                  = 0.87

let's calculate

         γ =

         γ = 0.49305

let's reduce the mass of the jack to SI units

         W = 8.5 lb (4.448 N / 1lb) = 37.808 N

         W = mg

         m = W / g

         m = 37.808 / 9.8

         m = 3.86 kg

let's look for energy

          E = 3.86 (3 10⁸ )² 0.49305

          E = 1.7 10¹⁷ J

let's reduce to take PJ

          E = 1.7 10¹⁷ J ( )

          E = 1.7 10² PJ

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
