Answer:
The distance traveled by the balloon is 10.77 m
Explanation:
velocity of the ball,  = 2 m/s south
 = 2 m/s south
velocity of the air,  = 5 m/s west
 = 5 m/s west
To determine the distance the balloon will travel after 2 seconds, first determine the resultant velocity of the balloon.
                                        | 2m/s
                                        |
                                        |
                                       ↓
       5m/s  ←------------------
the two velocities forms a right angled triangle and the resultant will be the hypotenuses side of the triangle.
R² = 5² + 2²
R² = 29
R = √29
R = 5.385 m/s
The distance traveled by the balloon is calculated as;
d = R x t
where;
 t is time of the motion = 2 seconds
d = 5.385 x 2
d = 10.77 m
Therefore, the distance traveled by the balloon is 10.77 m.
 
        
             
        
        
        
Answer:
w=3.05 rad/s or 29.88rpm
Explanation:
k = coefficient of friction = 0.3900
R = radius of the cylinder = 2.7m
V = linear speed of rotation of the cylinder
w = angular speed = V/R or to rewrite V = w*R
N = normal force to cylinder 
N=


These must be balanced (the net force on the people will be 0) so set them equal to each other.





There are 2*pi radians in 1 revolution so:

So you need about 30 RPM to keep people from falling out the bottom
 
        
             
        
        
        
Because of how it's worded the answer would most likely be number four                                                                                       
        
                    
             
        
        
        
Answer:
False because igneous rocks are formed from a volcano and sedimentary never move they stay in one spot
