initial velocity = 20 km/h
5.5 m/s
final velocity = 50km/h
13.8m/s
time = 10 seconds
a=final velocity -initial velocity/time
a = 13.8- 5.5/10
a= 8.3/10
a= 0.83m/s^2
5.5 m/s
final velocity = 50km/h
13.8m/s
time = 10 seconds
a=final velocity -initial velocity/time
a = 13.8- 5.5/10
a= 8.3/10
a= 0.83m/s^2
