A truck is moving with an acceleration of 2 m/s2 due to a constant horizontal force F. Suddenly, a hail storm starts with a constant rate of mass μ=20 kg/s getting deposited on the truck. Find the force needed to maintain the acceleration of the truck after 2 seconds. Take g=10 m/s2. Speed of the hailstorm is 2 m/s (perpendicular to the velocity of the truck) and mass of the truck is initially m0=50 kg.
