Force = ma = m(v-u)/t = (mv – mu)/t = change of momentum /time = rate of change of momentum

Momentum of an object changes from 100 kgm/s to 200 kgm/s in 2 seconds. What is the force applied on it?

Initial momentum, p1 = 100kg-m/s

Final momentum, p2= 200kg-m/s

Time,t= 2 s

Force,F = ?

Using the formula,

F= p2-p1/t

F= 200-100/2

F= 100/2

F= 50 N

The force applied is of 50 N.

Which machine changes the direction of force needed to do a task without changing the size or force needed?

A pulley system is a machine that changes the direction of the force needed to do a task without changing the size or force needed. It allows you to pull downwards to lift an object upwards.


How much plutonium is needed to run a reactor?

The amount of plutonium needed to run a reactor depends on the specific reactor design and size. Typically, a few kilograms to several hundred kilograms of plutonium may be required for a nuclear reactor. The concentration and purity of the plutonium play a significant role in determining the exact amount needed.


If 3 ml per kg what would 800 pounds be?

To determine the total volume of fluid needed for an 800-pound person at a rate of 3 ml per kg, you first convert pounds to kilograms. Since 1 kg is approximately 2.2 pounds, you would divide 800 by 2.2 to get the weight in kilograms. Then, multiply the weight in kilograms by 3 ml to find the total volume needed.


What is a simple machine that changes the direction of force needed to move an object but not the amount of force needed?

A pulley is a simple machine that changes the direction of the force needed to move an object without changing the amount of force required. By using a pulley, you can apply a downward force to lift an object upwards.


Which simple machine changes the direction of force needed to do a task without changing the size of the force needed?

A pulley is a simple machine that changes the direction of the force required to perform a task without changing the amount of force needed. By redirecting the force, pulleys make it easier to lift or move heavy objects.
