M/s 3. A ferryboat accelerates from rest at a rate of 0.500 m/s2.
a. What is the velocity of the boat after it has traveled 4.75 m?
b. What is the velocity if the boat has traveled 50 m?

a. Final velocity, V = 2.179 m/s.  

b. Final velocity, V = 7.071 m/s.

Explanation:

Given the following data;

Acceleration = 0.500m/s²

a. To find the velocity of the boat after it has traveled 4.75 m

Since it started from rest, initial velocity is equal to 0m/s.

Now, we would use the third equation of motion to find the final velocity.

Where;

Substituting into the equation, we have;

Taking the square root, we have;

Final velocity, V = 2.179 m/s.

b. To find the velocity if the boat has traveled 50 m.

Taking the square root, we have;

Final velocity, V = 7.071 m/s.

force tends to be low and long diustance masses are high
