Q3. Drag measurements were taken for a 5 cm diameter sphere in water at 20°C to predict the drag force of a 1 m diameter balloon rising in air with standard temperature and pressure. Given kinematic viscosity of water (v) = 10 X 106 m²/s and kinematic viscosity of air (v) = 1.46 X 10-5 m2/s. 1. Perform the Buckingham Pi theorem to generate a relationship for Fo as a function of the independent variables. Assume the drag Fo is...
a ball with mass 0.15 kg is thrown upward with initial velocity 20 m/sec from the roof of a building 30 m high
a ball with mass 0.15 kg is thrown upward with initial velocity 20 m/sec from the roof of a building 30 m high. there is a force due to air resistance of |v|/30, where velocity v is measured in m/sec.a. find the maximum height above the ground the ball reaches.b. find the time the ball hits the ground.you cannot use the kinematic equations.

A ball is thrown straight up at speed in the presence of gravity. (a) Ignoring air resistance at first, what is the maximum height the ball reaches? (b) Now include Newtonian (quadratic) air resistance, with drag coefficient c. Letting the direction point upwards, write down the equation of motion (be careful with the signs). (c) Solve the equation of motion to find v(t)(= (t)). Remember to check that v(0) = . (d) Without integrating anything yet, calculate the time at...
