Answer: 500 J is the work done.

How much work will have to be done on a ball of mass 580g to give it a momentum 500g CMS 1?

The work done is 250 J thanks.

How much work is needed to be done on a ball of mass 50 g to give it a momentum of 500 g/cm s?

Product of mass and velocity is defined as momentum and therefore, force is equal to rate of change of momentum with respect to time $ \to F = \dfrac{{dp}}{{dt}}$. Hence, work needed to be done on a ball of mass $50g$ to give it a momentum of $500gcm{s^{ – 1}}$ will be $25 \times {10^{ – 5}}J$.

How much work is needed to be done on a ball of mass 50 gram to give it a momentum of 500 grams per second?

Hence, work needed to be done on a ball of mass $50g$ to give it a momentum of $500gcm{s^{ – 1}}$ will be $25 \times {10^{ – 5}}J$.

When a ball is thrown vertically upwards its kinetic energy at maximum height is?

When a body is thrown vertically upwards against the force of gravity, its kinetic energy keeps on decreasing as its velocity decreases. At the maximum height, kinetic energy becomes zero, as the velocity of the body becomes zero at this moment.

What is the kinetic energy of a 50g ball?

Mass of ball = 50 g = 0.05kg (a) Kinetic energy of the ball =`p^2/ (2m)` `=p^2/ (2m)= (0.005)^2/ (2xx0.05)=`2.5 × 10 -4 J Concept: Definition of Work

How many joules of work is done by one newton?

1 joule of work is said to be done when a force of 1 newton displaces a body through a distance of 1 metre in its own direction. A boy of weight 40 kgf climbs up the 15 steps, each 15 cm high in 10 s and a girl of weight 20 kgf does the same in 5 s.

How do you calculate work equal to kinetic energy?

Here work is equal to kinetic energy. W = KE = p 2 2 m = 5 × 5 2 × 0.05 = 25 0.1 = 250 J. How this 19-year-old earns an extra $3600 per week. His friends were in awe when they saw how much money he was making.

How do you calculate how many joules does it take to stop a car?

You can do the math yourself, just be sure to properly covert your units, esp. km/hr to m/s, to get joules = kg m^2/s^2. Complex answer: As nearly all the work in stopping a car is converted to the heat generated via friction in the brakes, one is left to wonder if any work actually was done.
