9. A carnival attraction tests your strength by how far in the air you can drive a weight with a hammer. You are able to throw the hammer with a velocity of 31 ft/sec. The hammer starts at a position 2 feet off of the ground. a) How long is the hammer in the air? b) How high are you able to throw the hammer? c) How long does it take the hammer to reach that height? d) How high in the air is the hammer after 1 second?

2. A baseball is thrown vertically up with speed vo and is subject to a quadratic drag with magnitude f(v) = cu2. Choose coordinates with +y upward and write down the equation of motion for the upward journey. Solve the equation of motion by separating variables and express v(t) as a function of time. Note: dx S: 1 tan -1 a a

The trap-jaw ant, found throughout tropical South America, catches its prey by very rapidly closing its mandibles around  its victim. Shown is the speed of one of its mandible jaws versus time in microseconds. a. What is the maximum acceleration of the ant’s mandible? b. The mass of a trap-jaw ant’s mandible has been estimated to be about 1.3 x 10-7 kg. Estimate the maximum force exerted by one mandible.

C1. You observed a stone falling freely from a cliff. The time it took to fall is 4 s. How high is the cliff?

A roof worker loses his grip on his box of tools while working on a tall house. His box slides down the roof. The roof is angled at 29 degrees with the horizontal. The roof is made of a frictionless material. The box travels 5 m down the roof and then leaves the edge of it 12 m above the ground. a). Figure out the box's velocity as it leaves the house's roof? b). How far from the base of the house does the box hit the ground? c). By how much does the box clear the yard fence which is 1.8m tall and located 6.7m away from the base of the house? I TOOLS 5m 29° 12 m 1.8m 6-7m ENGL

9: An archer fires an arrow straight up into the air with a speed v0=35.6m/s. Neglect air resistance.   a. Find the maximum height, hℎ, in meters, reached by the arrow.  b.  In terms of known quantities, write an expression for the time the arrow is in the air until it returns to launch height.

The first active volcano observed outside the earth was discovered in 1970 on Io, one of the moons of jupiter. The volcano was observed ejecting material to the height of about 3x105m. Given the acceleration of gravity on Io is 1.8 m/s2. Find: a. The initial velocity of the ejected material. b. What is the velocity at half that height?
