What is the height of a building that an object is dropped from if it has a mass of 3 kg and hits the ground with a velocity of

Marizza181 [45]

Answer:

125 m

Explanation:

m = 3kg

v = 50m/s

u = 0m/s

a = +g = 10m/s²

s = H = ?

using the formula,

v² = u² + 2as

50² = 0² + 2(10)(H)

2500 = 20H

H = 2500/20

H = 125m

This physics problem is kinda complicated to my small brains...

Veronika [31]

Answer:

$\huge\boxed{\sf P.E. = 14700\ Joules}$

Explanation:

This work done is in the form of Potential Energy so we'll use the formula of Potential Energy.

Given Data:

Mass = m = 250 kg

Acceleration due to gravity = g = 9.8 m/s²

Height = h = 6 m

Required:

Work Done in the form of Potential Energy = P.E. = ?

Formula:

P.E. = mgh

Solution:

P.E. = (250)(9.8)(6)

P.E. = 14700 Joules

$\rule[225]{225}{2}$

Hope this helped!
