Each term in the equation has dimensions of velocity-squared (remember "a" here is acceleration which is velocity divided by time, so "as" is velocity x distance / time = velocity squared).
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
yes.
Using v2 - u2 = 2as where, v = final velocity u = initial velocity a = acceleration s = distance travelled we get v2 = u2 + 2as Substituting the values, we get v2 = 02 + (2 x 0.25 x 1000) so v2 = 500, therefore v = 22.36 The train will be travelling at 22.36 ms-1.
Using the physics formula: v2 = u2 + 2as v - final velocity u - initial velocity a - acceleration s - distance When the object leaves the ground it is being slowed down by gravity until it stops so the acceleration equals -9.8m/s2 and as it will stop at 2.5 meters v = 0. U is the value we want to find out: 02 = u2 + (2 *-9.8*2.5) 49 = u2 So the object must leave the ground at 7m/s. By the way this is ignoring air resistance.
arent u a science student? its simple. time,initial velocity,accelaration the formula is; v2=u2+2as here v is final velocity u is innitial velocity a is accelaration s will be3 the stopping distance okkkk!!

Velocity can be found either by following formulas, v2 = u2 - 2as or v = distance by time,etc
TO CALCULATE ACCELERATION OF BODY that is 'g' / 'a' use formula:a=v-u/t where u=0m/s.s=ut+1/2at2.v2-u2=2as or v2-u2=2gh.
yes.

the first equation of motion is v=u+at the second equation of motion is s=ut+1/2 at2 the third equation of motion is 2as=v2-u2
Using the physics formula: v2 = u2 + 2as v - final velocity u - initial velocity a - acceleration s - distance When the object leaves the ground it is being slowed down by gravity until it stops so the acceleration equals -9.8m/s2 and as it will stop at 2.5 meters v = 0.

The LCM is u3 + 8u2 - u - 8u2 - 1 = (u -1)(u + 1)u2 + 9u + 8 = (u + 8)(u + 1)Thus, the LCM = (u - 1)[(u + 1)(u + 8)] = (u - 1)(u2 + 9u + 8).
v2 = u2+ 2as where v squares is the final velocity , u squared is the initial velocity , a is the acceleration and s is the distance travelled. If it is free fall take a = 10m/s squared ( as gravity ).
apply the formula: v2 - u2 = 2as. Here v= 0; u = 19.6m/s; a = -g ,find s and that's max. heigth
u2 - 2u +1 = u2 - u - u + 1 = u*(u - 1) - 1*(u - 1) = (u - 1)*(u - 1) = (u - 1)2
