1.) A ball of mass 0.1kg is thrown straight up with an initial velocity of 19.6 m/s. in answering the following, neglect air resistance and only consider times after the ball has left the hand of the person throwing it. a.) Draw a free-body diagram of the ball indicating the directions and sources of all of the forces acting on it. To indicate sources, it suffices to use appropriate subscripts on the symbol you choose to represent the magnitude of...
A projectile of mass 1.400 kg is shot straight up with an initial speed of 27.0 m/s. (a) How high would it go if there were no air resistance? m (b) If the projectile rises to a maximum height of only 27.2 m, determine the magnitude of the average force due to air resistance. N

A ball is launched from a cliff that is 20.0 m above the surface of a very deep lake. SEE FIGURE. The initial speed is |v_1| = 40.0 m/s. The ball follows the one-dimensional trajectory schematically shown. Assume the magnitude of gravitational acceleration is g = 9.80 m/s^2. Neglect air resistance. The ball hits the water surface and moves downward toward the bottom of the lake with an UPWARD acceleration whose magnitude is |a| = 3.00 m/^2. (Scales shown in...
A ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?
If a ball is thrown straight down with an initial speed of 18 ft/s, what is the magnitude (ft/s) of the ball's velocity when it hits the ground? The ball starts at 50 ft in the air.
A ball is thrown straight up in the air with an initial speed of 40 m/s. Ignore air resistance and take g - 10m/s2. What is the speed of the ball when it reach 40 m above the ground? 20 m/s 2012 m/s 2/20 m/s 3720 m/s 20/3 mis
A ball of mass 0.083 kg is shot straight up in the air using a compressed spring. The spring has a spring constant of 328 N/m and is compressed by 0.05 m initially. The ball reaches a height of 0.252 m above the initial position. How much energy has dissipated due to frictional effects such as air drag ? (in J)
A bullet is shot straight up into the air. Its initial speed is 7.5 km/s. What height will it reach? Assume air resistance is absent.
A ball is shot horizontally from the top of a building with an initial speed of 45 m/s. The ball lands 180 m horizontally from the release point. a) Explain how you can find the time the ball is in the air and find the time. b) Explain how you can find the height of the building and find the height.
