A cat rolls up a hill. It’s initial Velocity is 10 m/s.n It’s final velocity is 0 m/s. The time was five seconds. Calculate Acceleration

Respuesta :

Answer:

[tex]\boxed {\boxed {\sf a= -2 \ m/s^2}}[/tex]

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

[tex]a=\frac{v_f-v_i}{t}[/tex]

The final velocity of the cat was 0 meters per second and the initial velocity was 10 meters per second. The time was 5 seconds.

[tex]v_f=0 \ m/s\\v_i=10 \ m/s\\t= 5 \ s[/tex]

Substitute the values into the formula.

[tex]a=\frac{0 \ m/s-10 \ m/s}{5 \ s}[/tex]

Solve the numerator.

  • 0 m/s-10 m/s= -10 m/s

[tex]a=\frac{-10 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= -2 \ m/s^2[/tex]

The acceleration of the cat was -2 m/s². The negative acceleration indicates slowing down or stopping.
