A girl flips a coin into a 50 m deep wishing well. If she flips the coin upwards with an initial velocity of 5 m/s:a) How high does the coin rise?b) How long does it take to get to this point?c) How long does it take for the coin to reach the bottom of the well?d) What is the velocity when the coin hits the bottom of the well?

3. In Physics, the height of a free-falling object at a given time t is given by h = –16t² + v,t + h., where v, is the initial velocity, and h, is the initial height. A student throws a ball upward from a height of 48ft, initially at 32 ft/s. What is the maximum height of the ball?

A thoughtful person on a bridge reflecting on his awesome Physics class sees a small stone by his feet. Hmm, he thought to himself. Using his foot he slowly nudged the stone off the surface of the bridge and using his cell phone he timed how long it took to hit the water, about 1.75 s. How high (m) is the bridge above the water? (neglect air resistance)

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

A bucket is thrown vertically down a well with a speed of 4.24 m/s, it takes 1.96 s for the bucket to reach the bottom of the well What is the height of the well?

A ball is thrown straight up with enough speed so that it is in the air for several seconds. Assume the positive direction is upwards.   Part A - What is the velocity of the ball when it reaches its highest point   Part B - What is its velocity 0.70s before it reaches its highest point?   Part C - What is the change in its velocity, v, during this 0.70s interval?   Part D - What is its velocity 0.70s after it reaches its highest point?   Part E - What is the change in velocity, v, during this 0.70s interval?   Part F - What is the change in velocity, v, during the 1.4s interval from 0.70s before the highest point is 0.70s after the highest point? (Caution: we are talking about velocity not speed)   Part G - What is the acceleration of the ball during any of these time interavals and at the moment the ball has zero velocity?

A baseball is thrown with an initial speed of 37.5 m/s at a 42.0° angle in the absence of air resistance. a) What is the maximum height reached by the baseball? b) What is the magnitude and direction of the baseball's velocity at t = 2.50 s? c) What is the ball's height when it has traveled a horizontal distance of 55.0 m?

A stone is thrown upward from a cliff at an angle of 35 degrees above the horizontal with a speed of 47 m/s. The stone hits the ground 5.0 s later. a) What is the x component of the stones initial velocity? v47.0m/s 35 O51.0m/s 041.0 m/s 38.5 m/s O270 m/s

Use the position function ?(?) = −4.9t2 + v0 + s0 for free-falling objects.  A rock is dropped from the edge of a cliff that is 176.4 meters above the water A. Determine the position function for the rock B. Find the velocity function for the rock. C. Find the velocity when t = 2 seconds. D. Find the time required for the rock to reach the surface of the water E. Find the velocity of the rock at impact with the water.

15) You are standing on a cliff 50 m high and throw a rock with an initial velocity of 20 m/s straight up so that the rock eventually lands at the base of the cliff (50 m below you). How long is the rock in the air? a) What is the maximum height of the rock? b) What is the final velocity of the rock? c)
