A boat travels 12.0 m while it reduces its velocity from 9.5 m/s to 5.5 m/s. What is the magnitude of the boat’s acceleration while it travels the 12.0 m?
|
|
1.3 m/s2
|
|
|
2.5 m/s2
|
|
|
3.0 m/s2
|
|
|
7.5 m/s2
|
Explanation:
Detailed explanation-1: -∴ Acceleration of the boat is-2. 5 m/s².
Detailed explanation-2: -The magnitude of the boats acceleration is 9.8 m/s.
Detailed explanation-3: -What will be the change in velocity each second if acceleration is 10 m/s/s? An acceleration of 10m/s/s means that every second, the velocity increases by 10m/s.
Detailed explanation-4: -And the symbol v stands for the velocity of the object; a subscript of i after the v (as in vi) indicates that the velocity value is the initial velocity value and a subscript of f (as in vf) indicates that the velocity value is the final velocity value.
