During takeoff, a plane goes from 0 to 50 m/s in 8s. what is its acceleration? halos fast is it going after 5 s? how far had it traveled by the time it reaches 50 m/s?

Answer : Its acceleration is,

The velocity after 5 s is, 31.25 m/s

The distance traveled by the time it reaches 50 m/s is, 200 m

Solution :

First we have to calculate the acceleration.

Formula used :

where,

a = acceleration

v = change in velocity = 50 - 0 = 50 m/s

t = time = 8 s

Now put all he given values in the above formula, we get

Therefore, its acceleration is,

Now we have to calculate the velocity after 5 second.

Formula used :

where,

v = final velocity

u = initial velocity = 0 m/s

a = acceleration =

t = time = 5 s

Now put all the given values in the above formula, we get

Therefore, the velocity after 5 s is, 31.25 m/s

Now we have to calculate the distance traveled by the time it reaches 50 m/s.

Formula used :

where,

s = distance traveled

Now put all the given values in the above formula, we get

Therefore, the distance traveled by the time it reaches 50 m/s is, 200 m

the answer should be in the picture.
