Question

Calculate the speed of an object having momentum 7.25 x 10^5 kg.m/s and mass 0.285 kg. Answer in units of m/s.

Answer 1

Answer:

speed is 25.43 85 x 10^5  m/s

Explanation:

momentum = 7.25 x 10^5 kg.m/s

mass = 0.285 kg

to find out

speed

solution

we have given mass and momentum so

to find speed we apply here momentum formula that is

momentum = mass × speed   ...................1

put here all value and find speed

speed = momentum / mass

speed = 7.25 x 10^5 / 0.285

speed = 2543859.649

so speed is 25.43 85 x 10^5  m/s
