At what speed must a 0.6 kg stone be thrown in order that it has a relativistic mass of 0.76 kg? (c = 3.00 x 10^8 m/s) (A) 0.39
exis [7]

Explanation:

It is given that,

Relativistic Mass of the stone, m₀ = 0.6

Mass, m=0.76\ kg

Relativistic mass is given by :

m=\dfrac{m_o}{\sqrt{1-\dfrac{v^2}{c^2}}}.........(1)

Where

c is the speed of light

On rearranging equation (1) we get :

v^2=c^2(1-(\dfrac{m_o}{m})^2)

v=c\sqrt{ (1-(\dfrac{m_o}{m})^2)}

v=c\sqrt{ (1-(\dfrac{0.6}{0.76})^2)}

v = 0.61378 c

or

v = 0.6138 c

So, the correct option is (c). Hence, this is the required solution.

What is the amount of work done when JoAnne throws a baseball 2 meters at a force of 40
sergiy2304 [10]

Answer:

Amount of work done by Joanne = 80 joule

Explanation:

Given:

Displacement of ball = 2 meters

Force applied = 40 newtons

Find:

Amount of work done by Joanne

Computation;

Work done = Force applied x Displacement

Amount of work done by Joanne = Force applied x Displacement of ball

Amount of work done by Joanne = 40 x 2

Amount of work done by Joanne = 80 joule
