Question

Q4. a) What does the given graph represent?
b) Calculate the displacement of an object in
the given graph​

Answer 1

valocity time (m/s) (s)... .

Answer 2

Explanation:

a) any object having a velocity of 5 m/s began to redardate ie. the velocity of the object began to decrease from point A with respect of time and after a certain time the velocity became 0 in the point B.

b) v= u + at

0 = 5+ 5a

a = - 5/5

Retardration = 1

v²=u²-2as

0 = 25-2s

s=25/2

the displacement = 12.5
