Question

A 1200 kg aircraft going 30 m/s collides with a 2000 kg aircraft that is parked and they stick together after the collision and are going 11.3 m/s after the collision. If they skid for 14.7 seconds before stopping, how far did they skid

Answer 1

83.055 m

Explanation:

According to the given scenario, the calculation of skid distance is shown below:-

`S = (1)/(2) * (u + v) * t`

Where

u = 11.3

v = 0

t = 14.7

Now placing these values to the above formula,

So,

`S = (1)/(2) * (11.3 + 0) * 14.7`

= 83.055 m

Therefore for computing the skid distance we simply applied the above formula i.e by considering the all items given in the question
