[SOLVED] Help on tis quadratic functions question Homework Statement The speed v m/s of a particle traveling from A to B at time t s after leaving A, is given by v =10t-t². the particle starts from rest at A and comes to rest at B. Show that the particle has a speed of 5m/s or greater for...

So won't the velocity be different?? since both mass are diff

But F=MA so if the mass is heavier won't it accelerate less than the lighter mass? so won't the final velocity be different?

OK Thanks so it was C instead of P. Question solved

[SOLVED] Help on Permuntation and Combination Question Homework Statement After a show ,they decided to divide into two groups of size four and five, to go for a supper in 2 taxis. In how many ways could this be done if george and sally were to be in the same taxi Homework Equations nCn...

What i dun understand is why do they have the same final velocity?

Is tis correct i still have to minus the resultant force times the total distance traveled by both of them like root 3² +4² =5 then 5x9=45 1/2mv² =102-45 v = 5.34m/s but i do not understand why i have to minus away the 45

What do u mean by addition of both masses. I have taken the frictional force into account in the (2x4)

Homework Statement A 4kg Ball and a 3kg block of wood were placed in an arrangement as shown below. When the ball was released it fell through the distance of 5m pulling the block of wood up the ramp. If the pulleys were well oiled and the surface of the ramp exerts a frictional force of 2N...
