At 4 seconds after starting, a cyclist is traveling 10 m/sec. At 6 seconds, he is traveling 20 m/sec. What is his average acceleration from 4 seconds to 6 seconds?

The average acceleration of the cyclist is 5 m/s²

Explanation:

Given;

initial velocity of the cyclist, u = 10 m/s

final velocity of the cyclist, v = 20 m/s

initial time of the cyclist, t₁ = 4 seconds

final time of the cyclist, t₂ = 6 seconds

The average acceleration is given by;

Therefore, the average acceleration of the cyclist is 5 m/s²

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
