The world record for pole vaulting is 6.15 m. If the pole vaulter’s gravitational potential is 4942 J, what is his mass?

Physics

N76 [4]2 years ago
8 0

From the calculations, the mass of the pole is 82 Kg.

<h3>What is potential energy?</h3>

The term potential energy has to do with the energy that is possessed  by a body by virtue of its position.

Given that;

height = 6.15 m

PE = 4942 J

mass = ??

g = 9.8 m/s^2

Now

PE = mgh

m = PE/gh

m =  4942 J/9.8 m/s^2 * 6.15 m

m = 82 Kg

Who pioneered the use of galvanoplastic compounds for preserving footprints and ballistics?
alukav5142 [94]

Answer:

Option D (Alphonse Bertillon) is the correct response.

Explanation:

  • He seems to have been a policeman turned biometrics expert from France. Forensic techniques such as forensic record analysis were developed by Bertillon.
  • To retain proof, he always pioneered or developed the use of such galvanoplastic compounds as molds for footsteps as well as ballistics. To research physical changes with age, Bertillon has developed a method focused on images of almost the same person’s performance.

All those other choices weren’t connected to the instance offered. So, the best one is the one described.

zavuch27 [327]

Answer:

Max height= 36000 meters

Total Time = 120 seconds

Explanation:

0 = U - at

U = at

U= 20*60

U= 1200 m/s

MAX altitude would be

(U²Sin²tita)/2g

Max height= 1200² *( SIN90)²/(2*20)

Time of FLIGHT

2 * 1200/20

2400/20

120 sec onds
