Question

Part A) A small turbo prop commuter airplane, starting from rest on a New York airport runway, accelerated for 19.0s before taking off. It's speed at takeoff is 50.0 m/s. Calculate the acceleration of the plane , assuming it remains constant. Part B) In this problem, how far did the plane move while accelerating for 19.0s?

Answer 1

a)a=2.63m/s^2

b)x=475.25m

Step-by-step explanation:

To solve the first part of this problem we use the following equation

Vf=final speed=50m/s

Vo=initial speed=0

t=time

a=aceleration

a=(Vf-Vo)/t

a=(50-0)/19=2.63m/s^2

B )

For the second part of this problem we use the following equation

X=(Vf^2-Vo^2)/2a

X=(50^2-0^2)/(2*2.63)=475.25m
