Answer:

1703.24J

Explanation:

Given parameters:

Mass of brick = 7.9kg

Height of building = 22m

Unknown:

Potential energy of the brick = ?

Solution:

The potential energy of a body is the energy at rest of the body. Mathematically;

P.E = mgh

m is the mass of the brick

g is the acceleration due to gravity

h is the height of the building

Insert the given parameters and solve;

P.E = 7.9 x 9.8 x 22 = 1703.24J

A body of mass 5.0 kg is suspended by a spring which stretches 10 cm when the mass is attached. It is then displaced downward an

Dominik [7]

Answer:

position as a function of time is y = 0.05 × cos(9.9)t

Explanation:

given data

mass = 5 kg

length = 10 cm = 0.1 m

displaced = 5 cm

to find out

position as a function of time

solution

we will apply here equilibrium that is

mass × g = k × length

put here value and find k

k = $\frac{5*9.8}{.01}$

k = 490 N/m

and ω is

ω = $\sqrt{\frac{k}{m} }$

ω = $\sqrt{\frac{490}{5} }$

ω = 9.9

so here position w.r.t time is

y = 0.05 × cosωt

y = 0.05 × cos(9.9)t

so position as a function of time is y = 0.05 × cos(9.9)t

If an 0.6kg apple is dropped from 0.5m height onto a seesaw and flips up a 0.25kg kiwi. To what height does that kiwi reach. Ass

natita [175]

answer

Height at which kiwi reach=1.2m

Solution

In this question we have given

mass of apple, $m_{a} =.6kg$

mass of kiwi, $m_{a} =.25kg$

height from which apple is dropped, $H_{a} =.5m$

Let the height at which kiwi reached is $H_{k}$

here,

We will apply law of conservation of energy

it means,

potential energy of kiwi= potential energy of apple

$m_{k}\times g\times H_{k}= m_{a}\times g\times H_{a}$ ......(1)

here g is gravitational acceleration

put values of $m_{k} , g, H_{k}, m_{a}$ and $H_{a}$ in equation 1

$.25kg\times H_{k}=.6kg\times .5m\\H_{k}=\frac{.3kg\times m}{.25kg} \\H_{k}=1.2m$

therefore, Height at which kiwi reach=1.2m
