WebThe problem is to calculate the work done on a particle to move it from the origin to a distance d away along the x axis by a force. F → = k x i ^ + y j ^ ( x 2 + y 2) 3 / 2. where k is a positive constant. I've fount that ∇ × F → = 0 so F → is a conservative force. If I set. V ( x, y) = − k ( x 2 + y 2) 1 / 2. then ∇ V = F →.
WebAnswer (1 of 3): The work done is 300 x 20 = 6000 N.m = 6000 J , and that’s all. The time taken to do the work does not influence the work itself. If you want to quantify the Power required to do the work in 30 seconds, then P=6000/30=200 W (watts). Web1.) How much work was done on the book between A and B? 2.)

WebApr 1, 2016 · Δ p = (W Δ t) / d Where Δp is the impulse and W is the work done. I think this question can be answered by combining the equations for impulse and work done. 1. The equation for impulse derives from Newton's second law of motion: F = (Δp)/ (Δ t) ⇒ Δ p = F Δ t Δp is the change of momentum, which is referred to as "impulse". 2. The equation for … dfa.state.ny.us loginWebFriction and Work In calculating work done, the actual resistance overcome is measured. This is not necessarily the weight of the object being moved.
