D. Calculations ,[object Object],GIVEN: v i = 10 m/s v f = 32 m/s t = 3 s a = ? WORK : a = ( v f - v i ) ÷ t a = (32m/s - 10m/s) ÷ (3s) a = 22 m/s ÷ 3 s a = 7.3 m/s 2 a v f - v i t

D. Calculations ,[object Object],GIVEN: v i = 0 mph v f = 45 mph t = 3 mins = 0.05hrs a = ? WORK : a = ( v f - v i ) ÷ t a = (45 mph – 0mph) ÷ (.05 hours) a = 45 mph ÷ .05 hrs. a = 900 mph a v f - v i t

D. Calculations ,[object Object],GIVEN: v i = 25 m/s v f = 10 m/s t = 30 s a = ? WORK : a = ( v f - v i ) ÷ t a = (10m/s - 25m/s)÷(30s) a = -15 m/s ÷ 30 s a = -0.5 m/s 2 a v f - v i t

D. Calculations ,[object Object],GIVEN: v i = 30 m/s v f = 0 m/s a = -3 m/s 2 t = ? WORK : t = ( v f - v i ) ÷ a t = (0m/s-30m/s)÷(-3m/s 2 ) t = -30 m/s ÷ -3m/s 2 t = 10 s a v f - v i t
