A physic student sets out to experiment on the effect of drag forces on a ball of mass m by giving the ball an initial velocity nu_0 upwards and then downwards as describe below. In both cases, the ball experiences a force of air resistance whose magnitude is given by F = -k nu Where k is a positive constant. The positive direction for all vector quantities is taken to be upwards. Express all algebraic answers in terms of m....

Two Thrown Balls 1 2 3 45678 A blue ball is thrown upward with an initial speed of 19.8 m/s, from a height of 0.6 meters above the ground. 2.4 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 8.9 m/s from a height of 22.3 meters above the ground. The force of gravity due to the earth results in the bals each having a constant downward acceleration of 9.81 m/s2....

(1 point) A soccer ball is thrown straight up a distance of 6.0 m and retums to your hand. Neglecting air resistance, you know that OA. the accelcration was constant throughout its motion B, the acceleration wฮ5 upward on the way up and downward on the way down О С, the speed was zero at the maximum height, but the velocity was never zero. D. the ball took longer to go up than come down. E. the velocity was constant...
