Question

2. An arrow accelerates from zero to 40 m/s in the 0.5 s it is in contact with the bowstring.

What is the average acceleration?

Answer 1

Step-by-step explanation:

1.The average acceleration

a=change in v/ change in t

= 40 - 0/0.5

=80m/s^2

Answer 2

80m/s²

Step-by-step explanation:

we can calculate acceleration using the formula,

a = ∆v/∆t

where ∆v is the change in velocity and ∆t is the time elapsed in changing the velocity. so on substituting the respective values, we get ,

a = (40-0)/ 0.5 m/s²

a = 40*10/5 m/s²

a = 80m/s²

and we are done!
