Answer:
Its speed will be 280 m/s
Explanation:
Constant Acceleration Motion
It's a type of motion in which the speed of an object changes by an equal amount in every equal period of time.
If a is the constant acceleration, vo the initial speed, vf the final speed, and t the time, vf can be calculated as:
[tex]v_f=v_o+at[/tex]
The object accelerates from rest (vo=0) at a constant acceleration of [tex]a=8\ m/s^2[/tex]. The final speed at t=35 seconds is:
[tex]v_f=0+8*35[/tex]
[tex]v_f=280\ m/s[/tex]
Its speed will be 280 m/s
