In order for a plane to take off, it must be traveling at 160mph and requires a runway of .7 mile. What is the constant acceleration required for the plane to take off. I am doing something wrong. I integrated velocity to get position, as well as integrating acceleration to get velocity. I am...

A car travelling at 100km/h takes 65 m to stop after the driver sees a child run on to the road chasing a ball. If the driver's reaction time is 0.25s, calculate the deceleration of the car. Thanks

;) hiii I realli need help with the below question... A bullet passes through a board, the velocity on entering being 1200 m/s and on leaving 1100m/s. how many such boards of equal thickness placed one behind the other will the bullet penetrate assuming constant retardation. :confused: Thanks...

Hey help me with this question :o A body moving with constant accelertion and starting from rest covers 9m in the eighth second. Find the acceleration Thankss:)

Hey I was wondering if anyone can help me on this problem below :) The velocity of a particle moving in a straight ine with uniform acceleration increases from 10m/s to 20m/s in 30m. When and where was the velocity 15m/s Thx:D
