Question

Oliver queen shots his arrow towards a target at a 1
distance of 90 m, and hits ‘bullseye’ . Calculate the acceleration and time taken by the arrow to hit the target with a velocity of 90.0 m/s.

Answer 1

The acceleration of the arrow is 90 m/^2.

Explanation:

We are given that:

Distance " S " = 90 m

Velocity "V" = 90 m/s

To Find: Acceleration "a" = ?

Time "t" = ?

Solution:

we know that:

a = v / t

To find acceleration first we need to calculate time.

Now

S = V x t

90 m = 90 x t

Time "t" = 90/90 = 1 s

The time is one second.

Now

Acceleration "a" = v / t

a = 90 / 1 = 90 m/s^2

Thus the acceleration of the arrow is 90 m/^2.
