Q. The third equation of motion

(v^{2} - u^{2} = 2 a s)

can be derived using first two equations of motion

(v = u + a t

and

s = u t + \frac{1}{2} a t^{2})

The correct equation of motion is :

(a) v=u+aS (b) v=ut+a

u = 24

m\s,

v = 10

m\s,

a = - 0.7

mpersecond square , find

t

An open box A is made from a square piece of tin by cutting equal squares S at the corners and folding up the remaining flaps. Another open box B is made similarly using one of the squares S. If U and V are the volumes of A and B respectively, then which of the following is not possible?

Derive following equations for a uniformly accelerated motion :
