A bus moving at 36 km/hr. is uniformly accelerated at 2m/s². Find its velocity after 5 seconds |
|
Answer» Given :Initial velocity = 36 km/hTherefore, 36×5/18 = 10m/s.Acceleration = 2m/s square.Time = 5 second.Using first equation of motion : v = u+at = 10+(2×5) =10+10 = 20m/s. Tried my best......✌️✌️ u=36km/h=10m/sA=2m/st=5sv=u+at =10+(2×5) =20v^2 - u^2=2as =20^2 - 10^2 --------------- =s 2×2 s=75m |
