Ответ:
t=1.25s
Explanation:
The formula is
a= (V1-V0) /t
t = (V1-V0)/a
V1=50m/s
V0= 0 m/s
a= - 4m/s2
t= (0-50)/-4 = 1.25s
Ответ:
Velocity equals displacement divided by time.
Acceleration equals change in velocity divided by time.
Average velocity can be found by using several velocities and their total time.
