Question

What is the acceleration of an hockey player who is skating at 10m/s and comes to complete to stop in 2 sec?​

Answer 1

Answer:

5 ms^-2

Explanation:

a =

$\frac{v}{t}$

=

$\frac{10}{2}$

therefore a = 5 ms^-2

Answer 2

Answer:

Acceleration = -5 m/s^2

Explanation:

Given:-

Initial velocity = u = 10 m/s

Final velocity = v = 0 m/s

Time = t = 2 sec

Let the acceleration be a.

a = v-u

t

= (0-10). m/s.

2 sec

= -10 m/s.

2 sec

= -5 m/s^2
