1. A ski-plane with a total mass of 1200 kg lands towards the west on a frozen lake at 30.0
igor_vitrenko [27]

Answer:

d = 229.5 m

Explanation:

It is given that,

Total mass of a ski-plane is 1200 kg

It lands towards the west on a frozen lake at 30.0  m/s.

The coefficient of kinetic friction between the skis and the ice is 0.200.

We need to find the distance covered by the plane before coming to rest. In this case,

\mu mg=ma\\\\a=\mu g\\\\a=0.2\times 9.8\\\\a=1.96\ m/s^2

It is decelerating, a = -1.96 m/s²

Now using the third equation of motion to find the distance covered by the plane such that :

v^2-u^2=2ad\\\\d=\dfrac{-u^2}{2a}\\\\d=\dfrac{-(30)^2}{2\times -1.96}\\\\d=229.59\ m

So, the plane slide a distance of 229.5 m.

in order to generate electricity, nuclear powerplants take advantage of this part of the electromagnetic spectrum
antiseptic1488 [7]
Bit of an odd question. Power Plants are known to use water-powered turbines to generate electricity, but can also make use of nuclear fission.

A). No. Condensation happens when you take heat out of a gas.

b). No.  I'm not sure what transpiration is.

<u>c). Yes.</u> Evaporation happens when you add heat to a liquid.

d). No.  Sublimation sometimes happens when you add heat to a solid.
