Question

Marcus is on a train that travels 20 m/ s and takes 5 seconds to slow to 10 m /s . how would marcus correctly calculate the acceleration?

Answer 1

Marcus is on a train that travels 20 m/ s and takes 5 seconds to slow to 10 m /s. The acceleration will be -2m/$s^{2}$

$v_{0}$=20 m/s

v=10 m/s

t= 5 sec

Acceleration would be

                              $a=\frac{v-v_{0}}{t}$

                              $a=\frac{10-20}{5}$

                              a = -2 $m/s^{2}$

What is Acceleration?

Rate of change of velocity with respect to time is known as Acceleration. Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time.

Formula for acceleration.

                                         $a=\frac{v-v_{0}}{t}$

Unit of acceleration is $m/s^{2}$.
