An object with a cross section A is shot horizontally across frictionless ice. Its initial velocity is Vo at to = 0. A drag force D (pointing West) is opposite in direction to the object's velocity. Assume the magnitude of D is equal to 0.25AU², A = 2.24 m², Vo = 20 m/s, m = 1500 kg. What is its velocity when t = 402 s? %3D See Fig. 2 19 m/s 16 m/s 12 m/s 5.0 m/s 10 m/s

An object with a cross section A is shot horizontally across frictionless ice. Its initial velocity is Vo at to = 0. A drag force D (pointing West) is opposite in direction to the object's velocity. Assume the magnitude of D is equal to 0.25AV², A = 2.24 m2, m², Vo = 20 m/s, m = 1500 kg. What is its velocity when t = 402 s? See Fig. 2 19 m/s 16 m/s 12 m/s 5.0 m/s 10 m/s
