Question

A footballs starts from rest 10 meters from the goal line and accelerates away from the goal line at 5.00 m/s². How far from the goal line is the player after 4.0 s?

a) 6.0 m
b) 30 m
c) 40 m
d) 50 m

Please answer and explain

Answer 1

Answer:

d

Step-by-step explanation:

h = 10+1/2 a*t*t

h= 50m

Answer 2

Answer:

Step-by-step explanation:

* The Player starts from rest. Therefore initial velocity(u) = 0

* Acceleration(a) = 5m/$s^{2}$

* Time(t)= 4s

*By applying the equation of linear motion

Displacement = ut + (1/2)a$t^{2}$

                       = 0 + 1/2 * 5 * $4^{2}$

                        =40m

**Here, the player has gone a distance of 40m from the starting point. Therefore, he has gone a distance of 50m away from the goal line (cuz distance between the starting point and the goal line =10m)

Therefore, Answer = d)50m
