Question

pls help me it is from physics

Answer 1

Answer:

Uniform circular motion is accelerated motion because it's velocity changes even it's in uniform speed but it's direction changes at each point and hence it is in accelerated motion

Distance - 2πr

2*22/7*45000

282,857.143

Speed - Distance/Time

282,857.143/42

6,734.69388 km/h
