Time = √(2h/g) = √(2 × 45 m/10 m/s²) = √(9) = 3 s

Acceleration = (Final Speed - Initial Speed)/Time = (100 km/h × (1000 m/3600 s))/10 s = 5 m/s²

Speed = Distance/Time = 60 km/1 h = 60 km/h

Speed = Distance/Time = 15 km/(30/60) h = 30 km/h

Speed = Distance/Time = 400 m/50 s = 8 m/s

Distance = Speed × Time = 15 m/s × (4 × 60 s) = 900 m

Time = Distance/Speed = 10 km/5 km/h = 2 hours

Distance = Speed × Time = 80 km/h × 2.5 h = 200 km

Average Speed = Total Distance/Total Time = 120 km/2 h = 60 km/h

Height = (Initial Speed)²/(2 × g) = (20 m/s)²/(2 × 10 m/s²) = 20 m
