Question

an aircraft travelling at 150m/s for 1 minute. f it accelerates at a rate of 10m/s^2 calculate the distance it travels

Answer 1

Answer:

=150msvi=150ms

a=10ms2a=10ms2

d=2km=2000md=2km=2000m

Where vivi is the initial velocity, aa is the acceleration and dd is the distance travelled. This is, at heart a basic kinematics question. In this case, we’ll use the formula d=vit+12at2d=vit+12at2.

Plug the information that you know into the equation. It should give us a quadratic:

2000=150t+12(10)t22000=150t+12(10)t2

Which simplifies to:

5t2+150t−2000=05t2+150t−2000=0

Solve the quadratic, and we get:

t=−40st=−40s or t=10st=10s

Explanation:

Time is not negative ,so time taken cover two kilometers is 10s.
