Question

drive the equation for positive time relation​

Answer 1

Answer:

Here's a word equation that expresses the relationship between distance, velocity and time: Velocity equals distance travelled divided by the time it takes to get there. Confident that his high typical velocity would allow him to cover the race distance in a short amount of time, the hare took a lot of breaks.

Answer 2

Answer:

hola mate ,

Here's your answer!!

Consider the graph shown in the given attachment.

Obviously, the total distance s travelled by the object in time t is given by are under v-t graph.

Therefore, distance travelled, s = Area OABGC

Given ,

Obviously, OABGC is a trapezium, whose area is (OA + BC/2) × OC.

But, OA = u, BC = v and OC = t

Distance travelled,

From the velocity - time relation,

we have

at = v - u or t = v - u/a

On substituting this value of t in equation, we get

$➡ v² - u² = 2as$

Therefore, this equation is the position velocity relation for uniformly accelerated motion.
