A particle is projected with velocity of 10 m/s in a resistive medium which offers retardation given by a = 5v. If velocity (in m/s) of particle as function of time t is given as v= 10e-kt then find k.help |

Answer» Given : v o
=10 m/s θ o
=60 o
ANGLE of inclination α=30 o
TIME of flight T= g cosα 2v o
sinθ o
⟹ T= 10×cos30 o
2×10×sin60 o
=2 s |
