A car traveling at 60.0 m/s forward slows down to 40m/s forward. In 2.5 seconds. Assuming that this acceleration continues, how many seconds would it take the car to slow to 12 m/s forward

Respuesta :

a,A = vf -vi/t

A = 40m/s -60 m/s/2.5s

A =- 20m/s /2.5s

A = - 200 m/s/25s

A = - 8m/s²

B,A = 12 - 60/2.5

A = - 48 /2.5

A = - 480/25

A= - 19.2 m/s²
