magma_saber said:so its 218.75 + 800 + 510?
The work done on a 70kg mass can be calculated by multiplying the force applied to the mass by the distance the mass moves in the direction of the force. The formula for work is W = F x d, where W is work, F is force, and d is distance.
The unit of measurement for work is joules (J).
The final velocity of a 70kg mass can be calculated using the formula v = √(2 x W/m), where v is final velocity, W is work, and m is mass. Alternatively, if the initial velocity (u) and acceleration (a) of the mass are known, the formula v = u + at can be used.
Work is the amount of energy transferred to or from an object by a force, while power is the rate at which work is done. In other words, work is a measure of the total energy involved, whereas power is a measure of how quickly that energy is being transferred.
Yes, the final velocity of a 70kg mass can be negative if it is moving in the opposite direction of its initial velocity. A negative final velocity indicates that the mass is decelerating or moving in the opposite direction of the applied force.
