A flower pot is knocked off a window ledge from a height d = 22.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h = 1.72 m who is standing below. Assume the man requires a time interval of Δt = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony...
A flowerpot is knocked off a balcony 23.9 m above the sidewalk and falls toward an unsuspecting 1.93 m tall man who is standing below. How close to the side walk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? Assume that the man below requires 0.138 s to respond to the warning, and the velocity of sound in air to be 341 m/s. The acceleration...
(1 point) A stone thrown upward from the top of a 72 ft cliff at 119 ft/s eventually falls to the beach below. (For this problem take the acceleration due to gravity to be g-32 ft/s2; take upwards to be a positive direction.) (a) How long does the stone take to reach its highest point? time (include units) (b) What is its maximum height? height- include units) (c) How long before the stone hits the beach? time (include units) (d)...
A bowling ball falls off the top of a building and hits the ground with a velocity of 40 m/s How high is the building? How long does it take?
A car falls off a cliff at 50 m traveling at 27 m/s. A) How long will it take the car to hit the ground B) How far will the car travel when it hits the ground C) what is the cars velocity upon impact?
With solutions please. Thanks. 1)A base-jumper jumps off a stationary balloon at 6000 ft, free-falls for 6 seconds at which point the parachute opens. After the chute opens, he decelerates to 18 ft/s in 3 seconds, and then drifts downwards at constant velocity to impact. Find maximum speed during this event. Hint: Break problem into three parts -free fall through deceleration after chute opening, and constant velocity b. Find total time. air where the object is accelerating downwards, motion. 2...
How long does it take an object to fall 12.5m? Ignore air resistance, and answer in seconds.
How long does it take a packet of 500 bytes length to propagate over a link of distance 1,500 km, propagation speed 2.5 x 10^8 m/s, and transmission rate 5 Mbps? More generally, how long does it take a packet of length L to propagate over a link of distance d, propagation speed s, and transmission rate R bps? Does this delay depend on packet length? Does this delay depend on transmission rate? Explain your choices.
A first-order reaction has a half-life of 20.8 s . How long does it take for the concentration of the reactant in the reaction to fall to one-fourth of its initial value?
