Question 1: Projectile motion in a constant gravity field A body of mass m = 1 kg, located 100 m above Earth's ground level, is kicked off hori- zontally with speed 2 m/s (see Fig. 1a). Assume that the gravity acceleration is constant (g = 9.81 m/s²). - How long after the initial kick-off will the body reach the ground? - - t₁ = What would be the horizontal distance covered by the body at this time? R = What its speed would be then? VR = - What is the total work produced/wasted from the gravity during the falling time? WR =
