Answer:
1. a = Vf - Vi / t
a = 45 m/s - 0 m/s / 3s
a = 45 m/s / 3s
a = 15 m/s²
2. a = Vf - Vi / t
a = 60 km/hr - 20 km/hr / 10s
a = 40 km/hr / 10s
a = 4 km/hr/s
3. t = Vf - Vi / a
t = 150 m/s - 50 m/s / 20 m/s²
t = 100 m/s / 20 m/s²
t = 5s
4. t = Vf - Vi / a
t = 0 m/s - 6000 m/s / -400 m/s²
t = -6000 m/s / -400 m/s²
t = 15s
5. a = Vf - Vi / t
a = 85 m/s - 33 m/s / 4s
a = 52 m/s / 4s
a = 13 m/s²
