1. What is the Formula's for Kinetic and Potential Energy?
Vilka [71]

Answer:

Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.

Verizon [17]

Answer:29.41 m/s

Explanation:

Given

Height of cliff 22.8 m

Height of river bank=2.4 m

width of river=60.0 m

Car can considered as projectile

Time travel to cover vertical distance=22.8-2.4=20.4 m

h=ut+\frac{at^2}{2}

20.4=0+\frac{gt^2}{2}

t^2=4.163

t=2.04 s

Range=60 m

Let u be the speed of car

ut=60

u=\frac{60}{2.04}=29.41 m/s

A 82-kg skydiver has a speed of 40 m/s at an altitude of 490 m above the ground. Calculate the total mechanical energy of the sk
Sav [38]

Answer:

ME=459,364J

Explanation:

Mechanical Energy=Potential Energy+ kinetic Energy

m=82kg,g=9.8N/kg,h=490m,v=40m/s

To calculate Kinetic Energy:-

KE=\frac{1}[2}mv^2\\=\frac{1}{2}\times82kg \times(40m/s)^2\\=65600J

To calculate Potential Energy:-

PE=mgh\\=82kg \times9.8N/kg \times490\\=393764

therefore,

ME=KE+PE\\=65600+393764\\=459364J

The skydiver's total mechanical energy is 459365J
