The drag force on a large ball that weighs 200 g in free flight is given by FD = 2*10 V , where FD is in Newtons and V is in meters per second. If the ball is dropped from rest 300 m above the ground, determine the speed at which it hits the ground. What percentage of the terminal speed is the result?

If a golf ball were dropped from a significant height and the force of Drag is modeled by Fd=0.0057*V-0.0106, where V is the velocity in m/s the Fd is the force of drag in N. The mass of the golf ball is 0.0455 Kg. h. How high will the golf ball bounce after the 5th impact with the concrete surface ignore drag force? i. If drag was included for G and H what type of analysis technique would be needed

When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 852 N and the drag force has a magnitude of 1018 N. The mass of the sky diver is 86.9 kg. Take upward to be the positive direction. What is his acceleration, including sign?

.A student engineer is given a summer job to find the drag force on a new unmaned aerial vehicle that travels at a cruising speed of 320 km/h in air at 15oC. The student decided to build a 1/50 scale model and test it in a water tunnel at the same temperature. (a) What conditions are required to ensure the similarity of scale model and prototype. (b) Find the water speed required to model the prototype. (c) If the drag...

Two carts with masses 250. g and 200. g are free to slide without friction on a horizontal airtrack. The 250.g cart is pushed against a spring, compressing it by 3.00 cm, then released. It slides towards the initially stationary 200 g mass and collides with it. After the collision the 200. g mass has a forward velocity of 0.450 m/s and the 250. g mass has a forward velocity of 0.250 m/s. a) What was the velocity of the...

A 200 g solid plastic ball (i.e., an insulator) with a 30 cm radius has a total charge of -20 μC that is uniformly distributed throughout its volume. The center of the ball is at the origin. A –5 μC point charge with a mass of 30 g is placed on the x-axis, 100 cm away from the center of the ball. Both charged objects are held in place. a) Find the electric field (magnitude and direction) at the following...

A 100 g ball moving to the right at 4.0 m/s collides head-on with a 200 g ball that is moving to the left at 3.0 m/s. If the collision is perfectly elastic, what are the speeds of each ball after the collision? (Vfx)1 and (Vfx)2 What is the direction of 100-g ball after the collision? upward, downard, to the right, to the left? What is the direction of 200-g ball after the collision? upward, downward, to the right, to...
