Question

1. A cyclist accelerates uniformly from rest at point A and reaches point Y at a velocity of 9 m/s. The cyclist covers the last 10 m of her ride in 2 s. Determine the acceleration of the cyclist?

Answer 1

its answer is 4.5 m/s^2

Answer 2

                        Q) A cyclist accelerates uniformly from rest at point A and reaches point Y at a velocity of 9 m/s. The cyclist covers the last 10 m of her ride in 2 s. Determine the acceleration of the cyclist⬇?

Answer:- ⬇

                         Given :-

                                       u = 0

                                       v = 9 m/s^2

                                       s = 10 m

                                       t = 2 sec

                                       a = ? ( to be calculated )

As,

        we know that

                              v^2 = u^2 + 2as

                              (9)^2 = (0)^2 + 2*a*10

                               81 = 20 *a

                               a = 81 /20

                                a = 4.05 ≈  4m/s^2
