A train moving at 30km/h accelerates to a speed of 50km/h in 30s. find the average acceleration in m/s² ​

Respuesta :

Answer:

Explanation:

a= (v-u)/t where v = the final velocity at 50m/s, u= the inital velocity at 30m/s and t= the time taken at 30 seconds

a=(50-30)/30

a= 2/3m/s^-2 or 0.67m/s^-2  (m/s^-2 is the units for accelaration)
