- A man (mass 45 kg) shoots himself out of a cannon straight upward with an initial velocity of 46 m/s towards a ledge 95 m above the cannon. There’s some air resistance occurring, and the man’s upward trajectory ends 6.0 meters below the ledge. A) What was the average force of frictional air resistance the man experienced during his upward motion? B) Assuming the same average air resistance on the way down, how fast will the man’s impact velocity be when he returns to the “ground” level of the cannon’s muzzle? Please answer the question on paper. I do not understand when it is typed out. Thank youA bowling ball is dropped from the top of a building that has a height of h = 112 m. Part (a) Assuming air resistance is negligible, what is the ball's speed, vf in m/s, when it strikes the ground?Part (b) If drag produces an opposing force of 10 N while the ball's falling, what is the ball's speed, vf in m/s, when it strikes the ground? Assume the ball has a mass of 5 kg.Part (c) A different ball was dropped and the final speed was measured to be vf = 8.5 m/s while the drag force was measured to be 50 Newtons. What is the mass of this ball in kg?A bartender slides a mug of root beer with mass m - 2.4 kg down a bar top of length L 1.8 m to an inattentive patron who lets it fall a height h 1.4 m to the floor. The bar top (see figure below) is smooth but still has a coefficient of kinetic friction of HK 0.078. (Assume up and to the right as the positive directions.) (a) If the bartender gave the mug an initial velocity of 2.5 m/s, at what distance D from the bottom of the bar will the mug hit the floor? 0.9996 m (b) What is the mug's velocity (magnitude and direction) as it impacts the floor? Magnitude 75 Direction (counterclockwise from the +x-axis) 68.9 X m/s x ° (c) Draw velocity time diagrams for both the x and y directions for the mug, from the time when the bartender lets: go of the mug to when it hits the floor.
