Quiz about Kinematic Equations

Question 1

What's the missing part in the given Kinematic Equation?

$$d\ =\ \frac{v_f\ -\ v_i}{2}\ imes\ -$$

Accepted Answer

$$t$$

Answer

$$t^2$$

Answer

$$a$$

Answer

$$d$$

Question 2

Which of the below kinematic equations is correct?

Accepted Answer

$$d\ =\frac{v_{f\ }+\ v_i}{2}\ imes\ t$$

Answer

$$v_{f\ }=\ v_i\ \ +\ a\ imes\ d$$

Answer

$$v_{f^2\ }\ =\ v_{i^2\ }\ +\ a\ imes d$$

Answer

$$v_{f^2\ }=\ v_{i^2\ }\ -\ 2\ \left(a\right)\left(d\right)$$
