Equations of the vertical launch:
Vf = Vo - gt
y = yo + Vo*t - gt^2 / 2
Here yo = 35.0m
Vo is unknown
y final = 0
t = 4.00 s
and I will approximate g to 10m/s^2
=> 0 = 35.0 + Vo * 4 - 5 * (4.00)^2 => Vo = [-35 + 5*16] / 4 = - 45 / 4 = -11.25 m/s
The negative sign is due to the fact that the initial velocity is upwards and we assumed that the direction downwards was positive when used g = 10m/s^2.
Answer: 11.25 m/s
        
                    
             
        
        
        
Answer:
the ratio of Hank's mass to Harry's mass is 0.7937 or [ 0.7937 : 1 
Explanation:
Given the data in the question;
Hank and Harry are two ice skaters, since both are on top of ice, we assume that friction is negligible.
We know that from Newton's Second Law;
Force = mass × Acceleration
F = ma
Since they hold on to opposite ends of the same rope. They have the same magnitude of force |F|, which is the same as the tension in the rope.
Now,
Mass × Acceleration
 × Acceleration = Mass
 = Mass × Acceleration
 × Acceleration 
 
so
Mass /  Mass
 /  Mass = Acceleration
 = Acceleration / Acceleration
 / Acceleration 
 
given that; magnitude of Hank's acceleration is 1.26 times greater than the magnitude of Harry's acceleration,
Mass /  Mass
 /  Mass = 1 / 1.26
 = 1 / 1.26 
Mass /  Mass
 /  Mass = 0.7937 or [ 0.7937 : 1 ]
 = 0.7937 or [ 0.7937 : 1 ]
Therefore, the ratio of Hank's mass to Harry's mass is 0.7937 or [ 0.7937 : 1 ]
