Question1
An arrow is fired with a speed of 18.0 m/s at a block of Styrofoam resting on a smooth surface. The arrow penetrates an assured distance into the block before coming to rest relative to it. Throughout this process the arrow's deceleration has a magnitude of 1450 m/s2 and the block's acceleration has a magnitude of 450 m/s2
Question2
A plane accelerates from rest at a constant rate of 5.00m/s^2 along a runway that is 1800m long. Imagine that the plane reaches the necessary takeoff velocity at the end of the runway. What the time t_ {rm is TO} needed to take off?
