A ball is thrown vertically upward at 10m/s. How high will it get, how long will it be in the air, and how fast will it be moving when it hits the ground? Step 1: Write the given Initial velocity (upward)= 10 m/s Step 2: Determine the formula/s that may be utilized For upward direction: For downward direction: Step 3: Find the maximum height of the ball Use the eq 3 for upward direction In order to find hte max height, use 0 m/s as the final velocity (0 m/s)²=(10 m/s)²-2(9.81 m/s²)(max height) 10²=2*9.81*max height The maximum height of the ball will reach is 5.10 meters. Step 4: Find the time it will stay in the air For upward motion, use equation 1 0 m/s= 10 m/s-(9.81 m/s²)(t upward) The time it will take to reach the maximum height is 1.02 sec. For downward motion, use equation 2 5.10 meters=(0 m/s)(t downward)+(1/2)(9.81 m/s²)(t downward)² The time it will take to reach the ground from maximum height is also 1.02 sec. The total time the ball will be in the air ...
What did the Sherman antitrust act do during the progressive era Sherman Antitrust Act of 1890 or "Anti-monopoly law" The law attempts to prevent the artificial raising of prices by restriction of trade or supply. Alan Greenspan, exFED chairman in his essay described the Sherman Act as stifling innovation and harming society. "No one will ever know what new products, processes, machines, and cost-saving mergers failed to come into existence, killed by the Sherman Act before they were born. " Greenspan summarized the nature of anti-monopoly law as: "a jumble of economic irrationality and ignorance."
