-- An A300 Airbus commercial jet airliner, loaded with passengers, cargo,
and flight crew, cruising in a straight line, at 35,000 ft altitude, at a constant
speed of 530 miles per hour.
Net force is 5000 - 1000 = 4000 N
F = ma
4000 = 200a
a = 20 m/s^2
Answer:
B. 24.2 m/s
Explanation:
Given;
mass of the roller coaster, m = 450 kg
height of the roller coaster, h = 30 m
The maximum potential energy of the roller coaster due to its height is given by;
Therefore, the maximum speed of the roller coaster is 24.2 m/s.
