A sustained force of 56 moves a model airplane 16 along its runway to provide the required speed for takeoff. Find the kinetic energy at takeoff. What is the formula?

A horizontal force of F = 130 N is applied to a 35-kg cart across a 10-m level surface. If the cart accelerates at 2.3 m/s2, then what is the amount of work done by the force of friction as it acts to retard the motion of the cart?

A skier reaches a speed of 42 m/s on a 25◦ski slope. Ignoring friction, what was the distance along the slope the skier would have had to travel, starting from rest?

I don't understand how you get the M. I know that M = moles/L, but the problem gives mg and ml so how do we find the molarity?

W = fd W also = change in K

b) it would be V1<V2

Should number two be.. (p*q)^k * (1-p*q)^(n-k)*(fact(k))/(fact(n-k)*fact(k)) OR (p*q)^k * ((1-p)*q)^(n-k)*(fact(k))/(fact(n-k)*fact(k)) ?

Dude idk im also doing the same thing atm
