A cyclist is moving along a straight line with uniform acceleration. After travelling from 20 seconds, the velocity of the cyclist is 3.5 m/s. Find the acceleration of the cyclist.

a = 0.175 m/s^2

Explanation:

From newtons eauations of motion we know

v=u+at

here v= final velocity, u= initial velocity, a = acceleration, t= time

u = o( initialy object must be at rest)

therefore, 3.5 = 0+ a(20)

⇒ a = 3.5/20 =0.175 m/s^2

explanation:

its math

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
