how do i find the amount of work done when given mass and speed?
To find the amount of work done when given mass and speed, you need to use the equation for work:
Work = Force x Distance
In this case, since you are given mass and speed, you need to calculate the force first. The force can be calculated using Newton's second law of motion:
Force = mass x acceleration
The acceleration can be calculated using the equation:
acceleration = change in velocity / time
However, since you are given speed instead of velocity and time, you need to convert speed to velocity. Velocity is a vector quantity and has a direction, while speed is a scalar quantity and only has magnitude. If the direction is not given, assume it to be in a straight line.
Once you have the force, you can then calculate the work done by multiplying the force by the distance traveled.
