Answer 1

Step-by-step explanation:

Given parameters:

Distance covered = 16m

Time = 6s

Initial velocity = 0m/s

Unknown:

Magnitude of the acceleration of the runner = ?

Solution:

To solve this problem, we have to apply the right motion equation which is given below;

S = ut +
`(1)/(2)` at²

S is the distance

u is the initial velocity

t is the time taken

a is the acceleration

Now, insert the parameters and solve for acceleration;

16 = (0 x 6) +
`(1)/(2)` x a x 6²

16 = 18a

a =
`(16)/(18)` = 0.89m/s²
