A penny is dropped from the observation deck of the Empire State building (215.0 m above ground). With what velocity would it strike the ground if air resistance were negligible? Assume the free-fall acceleration g = 9.80 m/s2. Ignore air resistance. If the velocity is downward, enter a negative value and if the velocity is upward, enter a positive value. answer in m/s
1b. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. What are the components of the initial velocity? v0x = ____m/s v0y = ____m/s
A crow flies carrying a shiny rock. The crow reaches an altitude of 65m and is flying 34.5 m/h. It releases the rock. Find the time it will take the rock to hit the ground below, the horizontal distance the rock will travel before it hits, and the speed of the rock when it hits the ground
A ball is kicked with an initial horizontal velocity of 16 m/s and initial vertical velocity of 10 m/s. What is the maximum height the ball goes above the ground? Use g = 10 m/s2.
A ball is thrown upward from a height of 1.6 m at an initial speed of 24 m/sec. Acceleration resulting from gravity is −9.8m/sec2. Neglecting air resistance, solve for the velocity v(t) and the height h(t) of the balltseconds after is is thrown. Ans...Velocity v(t)=_________meters/second
Suppose a Chinook salmon needs to jump a waterfall that is 1.35 m high. If the fish starts from a distance 1.16 m from the base of the ledge over which the waterfall flows, find the x- and y-components of the initial velocity the salmon would need to just reach the ledge at the top of its trajectory. v0x = m/s v0y = m/s
Consider a grey squirrel falling from a tree to the ground. Use a coordinate system in which positive is downward for this problem. a) Find the squirrel’s velocity, in meters per second, just before hitting the ground when it falls from a height of 1.3 m. Ignore air resistance. b) The squirrel softens its landing by bending its legs when it touches the ground, thereby stopping itself over a distance of 7.6 cm. Assuming a constant rate of deceleration, find the squirrel’s acceleration during this process, in meters per second squared.

Suppose a Chinook salmon needs to jump a waterfall that is 1.45 m high. If the fish starts from a distance 1.12 m from the base of the ledge over which the waterfall flows, find the x- and y-components of the initial velocity the salmon would need to just reach the ledge at the top of its trajectory.
