What is the work Sarah,60kg does against gravity is she goes up a 4m high stairwell in 3 seconds?

ladessa [460]

Work can be obtained from the following expression

W = F*d

Where F is the force (In this case the force it takes to lift Sarah, which is mass*gravity)

And d is the distance traveled.

W = 60kg*9.8m/s^2 * 4m = 2352 Joules

an object with a mass of 5kg is moving with an initial velocity of 20m/s.the object accelerates at a rate of 15m/s/s for 8s.what

Alinara [238K]

It doesn't matter what the object's initial velocity is, or how long
the acceleration lasts. All that matters is the object's mass and
acceleration.

Force = (mass) x (acceleration) =

(5kg) x (15 m/s²) =

75 kg-m/s² = <em>75 newtons .</em>
