Answer the entire problem set by using kinematic equations. Your answers must be rounded off to two decimal places. If the numerical answer exceeds 1000, do not use a comma as for 1,000.
An airplane accelerates down a runway at 4.50 m/s2 for 45.6 s until it finally lifts off the ground. Determine the distance traveled before takeoff.
If we apply the above equations to the case of an object that does not change its
direction of travel as it moves with constant acceleration, we find that the object:
Undergoes a displacement Ax = x- x, . Note that displacement is a positive
quantity if x > x, and a negative quantity if x < x,.
Has average velocity v = (x - x )/t = (v + vo)/2. Note that velocity has the same
sign as displacement.
Travels distance d = |Ax| = |x – x,| . Note that distance is always a positive
quantity.
Has average speed d/t . Note that speed is always a positive quantity.
Has constant acceleration a = (v – vo)/t . Acceleration may be positive or
negative, depending on how velocity changes.
