No. Acceleration Initial Velocity 1 2 20 km/h 10 m/s 3 4 5 50 m/s 0 km/h 2 m/s 80 m/s Time 2 h| Final Velocity 80 km/h 70 m/s 34 m/s 6 s 100 km/h 5 s 2h 12 s

— When we say acceleration, that is a vector quantity can be define as a rate in which an object change it's velocity. When an object is accelerating if it is changing it's velocity.

To solve the problem, we must use the formula when finding acceleration:

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

This formula has Initial Velocity [tex] (v_i) [/tex], Final Velocity [tex] (v_f) [/tex], and the Time [tex] (t) [/tex].

For item #1:

[tex] \boxed{\begin{array}{c} a = \frac{80-20}{2} = \frac{60}{2} = 30\:km/h^2 \\ \end{array}}[/tex]

For item #2:

[tex] \boxed{\begin{array}{c} a = \frac{70-10}{5} = \frac{60}{5} = 12\:m/s^2 \\\end{array}}[/tex]

For item #3:

[tex] \boxed{\begin{array}{c} a = \frac{80-50}{6} = \frac{30}{6} = 5\:m/s^2 \\\end{array}}[/tex]

For item #4:

[tex] \boxed{\begin{array}{c} a = \frac{100-\cancel{0}}{2} = 50\:km/h^2\\\end{array}}[/tex]

For item #5:

[tex] \boxed{\begin{array}{c} a = \frac{34-2}{12}=\frac{32}{12} = 2.66\:m/s^2 \\ \end{array}}[/tex]
