A1000-kg aircraft going 25 m/s collides with a 1500-kg aircraft that is parked. they stick
together after the collision and are moving at 10 m/s. if they skid for 9.7 seconds before
stopping, how far (in meters) did they skid?

48.54 m

Explanation:

Mass of moving aircraft = 1000 kg

Mass of stationary aircraft = 1500 kg

Velocity of moving aircraft = 25 m/s

Velocity by which they both move together = 10 m/s

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

Both planes skid a distance of 48.54 m

the answer would be 32*f
