An object moving with speed 6.25m/s is decelarated at given by dv /dt =-2.5root where v is instaneous speed. The time taken to rest
We have dv/dt = -2.5 v^1/2dt = dv/ -2.5 v^1/2So the total time taken isOn integratingt = [-0.8 v^1/2]06.25 t = 2 sec.So the object would take two seconds to come to rest.
Dear Student,Please find below the solution to your problem.We havedv/dt = -2.5 v^1/2dt = dv/ -2.5 v^1/2So the total time taken isOn integratingt = [-0.8 v^1/2]06.25t = 2 sec.So the object would take two seconds to come to rest.Thanks and Regards
