A body of mass of 150gk dropped by a parachute with negligible initial velocity. While the parachute is opening the motion is resisted by a force of 30V N,where v is in m/s,the velocity of the body.If the parachute is fully open at the end of 5s,prove that the velocity will be 5g(1-e^-1)m/s.The subsequent motion is resisted by force of 10v^2N. find the minimum safe dropping height given the impact velocity must not exceed (0.2g)^1/2 m/s Please show and explain ALL and work.
