Question

an object in a horixontal circle with a uniform speed. At t=0 the velocity given by u =20i+35j km/s. after one minute the velocity becomes u =-20i-35j . what is the magnitude of f the acceleration....
whoever solves this gets follower.....​

Answer 1

Answer:

80.6

Explanation:

v=u+at

20i+35j=-20i-35j +0

40i+70j =0

a2 = 40*40+35*35

a= 80.6
