Question

Question 5 of 10

Answer 1

a= v (1) - v (2)/ t = 14 - 10/20 = 4/20 = 0.2 m/s^2 south

Answer 2

Answer:

$a = 0.2 m/s^2$ towards North

Explanation:

Acceleration is defined as rate of change in velocity

So we will have

$a = \frac{v_f - v_i}{\Delta t}$

now we will have

$v_f = 10 m/s$

$v_i = 14 m/s$

time taken by it

$\Delta t = 20 s$

now we will have

$a = \frac{10 - 14}{20}$

$a = -0.2 m/s^2$
