Average acceleration = (change in speed) / (time for the change)
The missile's change in speed is (5,000 - 0) = 5,000 m/s
Average acceleration = (5,000 m/s) / (10 sec)
= 500 m/s² (about 51 Gs)
Inconveniently, this isn't one of the choices on the list. Is there something wrong, either with the choices or with my solution ?
No. Relax. Everything is OK.
500 meters is the same thing as 0.5 kilometer. So my answer can also be written as 0.5 km/s² . That doesn't change anything, and it IS one of the listed choices.
The average acceleration is <em>0.5 km/sec² (d)</em> .

hope this helped :) have a goodday
Answer:
0.61°
Explanation:
Since the box move at constant velocity, it means there is no acceleration then we can say it has a balanced force system.
Pulling force= resistance force
From the formula for pulling force,
F(x)= Fcos(θ)
= 425×cos(35.2)
=347N
The force exerted downward at an angle of 35.2° below the horizontal= Fsin(θ)= 425sin(35.2)
=425×0.567=245N
Resistance force= (325N+ 245N) (α)= 570N(α)
We can now equates the pulling force to resistance force
570 (α)= 347N
(α)= 347/570
= 0.61
Your answer is electricity, light and magnetism. They can be determined usinf elecromagnetic radioation.

Even the energy can't be detected by our eyes, there are a lot of measurement instruments that can measure infrared (IR), gamma rays, radio or X-rays or ultraviolet (UV)</span>
Do u know Chinese ?if yes I can explain to u easily
