Respuesta :

The acceleration of the bus is 1.11 meters per second square to the direction of motion

Explanation:

Acceleration is the rate of change of velocity

The formula of the acceleration is [tex]a=\frac{v_{2}-v_{1}}{t}[/tex] , where

  • [tex]v_{1}[/tex] is the initial velocity
  • [tex]v_{2}[/tex] is the final velocity
  • t is the time

A bus that goes  from 10 km/h to a speed of 50 km/h in 10 seconds

→ [tex]v_{1}[/tex] = 10 km/h

→ [tex]v_{2}[/tex] = 50 km/h

→ t = 10 seconds

Change the unite of the time from seconds to hour

→ 1 hour = 60 × 60 = 3600 seconds

→ 10 seconds = [tex]\frac{10}{3600}=\frac{1}{360}[/tex] hour

Substitute these values in the formula of the acceleration above

→ [tex]a=\frac{50-10}{\frac{1}{360}}[/tex]

→ a = 14400 km/h²

To change the unit of acceleration to meter per second change the

  kilometer to meter and the hour to seconds

→ 1 km = 1000 m

→ 1 hour = 3600 seconds

→ [tex]a=\frac{14400*1000}{(3600)^{2}}=\frac{10}{9}[/tex]

→ a = 1.11 m/sec².
