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
Answer:
you know what I think you should not give these kind of q
Answer:
1400 units of momentum.
Explanation:
Using the formula p=mv. We can get the momentum using 70*20 =1400 units of momentum
The fluids that have no resistance or zero resistance to internal friction are known as non- viscous fluids. • The fluid which has more resistance to flow is called viscous fluid. Viscosity is a property of a fluid, which is a degree of the amount of resistance between the fluid layers.
