Answer 2

Answer:

When an object moves in a circular path with equal intervals of time and covers equal distance.

Three equations of motions are :

v = u + at

S = ut+ ½at²

v²-u² = 2as

Where v is final velocity, u is initial velocity , t is time , S is distance and a is acceleration....

u = 0 m/s¹

v = 72 Km/hr¹ = 20m/s¹

t = 10s

a = ?

v = u + at

20 = 0+a(10)

20 = 10a

a = 2m²
