When an airplane is in level flight, its weight is balanced by a verticallift, which is a force exerted by the air. How large is the lift on an airplane in such flight if the mass ofthe airplane is 1.20 x 10 cubed kg.?
its weight is just
F = ma
= 1.2x10^3 * 9.8 = 1.176x10^4
the same airplane that was filled with 13 quarts of oil flies a distance of 3,300 miles. What is the average speed, in miles per hour of that airplane
To determine the lift on an airplane in level flight, we need to use the equation:
Lift = Weight
The weight of an object can be calculated using the equation:
Weight = mass × gravitational acceleration
Given:
Mass of the airplane = 1.20 × 10^3 kg
Gravitational acceleration = 9.8 m/s^2
Let's substitute the given values into the equation to find the lift:
Weight = (1.20 × 10^3 kg) × (9.8 m/s^2)
Weight = 1.176 × 10^4 N
Therefore, the lift on the airplane in level flight is 1.176 × 10^4 Newtons.
To calculate the lift on an airplane in level flight, you need to use the equation:
Lift = Weight of the airplane
The weight of an object is given by the equation:
Weight = Mass × Acceleration due to gravity
The mass of the airplane is given as 1.20 × 10^3 kg, and the acceleration due to gravity is approximately 9.8 m/s^2.
Substituting these values into the equation, we have:
Weight = (1.20 × 10^3 kg) × (9.8 m/s^2)
Weight = 11.76 × 10^3 kg·m/s^2
Now, since the lift is equal to the weight of the airplane, we can say:
Lift = 11.76 × 10^3 kg·m/s^2
Therefore, the lift on the airplane in such flight is approximately 11.76 × 10^3 kg·m/s^2.
