Sees a bus 1 km aheadof him moving with velocityof 10m/s with what speedthe scooterist should move so as to overtake the bus in 100 s |
Answer» Given:t = 100s, s = 1000m; V = 10m/s. But this is the RELATIVE speed with respect to the bus To Find:speed of the scooterist so that he should move so as to overtake the bus in 100 s. Solution:Vs - actual VELOCITY of speed of the the scooterist so that he should move so as to overtake the bus in 100 s; Vb = velocity of bus; v = relative velocity of SCOOTER with respect to bus. v = Vs-Vb as both busand scooter are MOVING in same direction. 10 = Vs-10; 10 + 10 = vs 20 = vs So, Vs = 20m/s |
