Answer:

Part b)

Part c)


Explanation:
The two components of the velocity of the ball is given as




Part a)
now we know that the displacement in y direction is given as

so we have



Part b)
Distance of the ball in x direction of the motion is given as



Part c)
In x direction the velocity will remain the same always

while in Y direction we can use kinematics



 
        
             
        
        
        
Answer:
4523.17365 Pa
Explanation:
m = Mass of plane = 77000 kg
F = Force = Weight = 
g = Acceleration due to gravity = 9.81 m/s²
A = Total area of wings = 167 m²
The pressure difference would be

The pressure difference required to keep the plane aloft is 4523.17365 Pa
