- We are standing on the top of a 1040 feet tall building and launch a small object upward. The object's height, measured in feet, after t seconds is h(t) = 16t? + 128t + 1040. A) What is the object initial velocity? ft/second B) What is the highest point that the object reaches? feetTHE CLIFF: Suppose a person is standing on the edge of a cliff, and throws a ball straight up in the air at an initial speed vo such that when it falls, it will go to the base of the cliff 50.0 m below as in the figure. It takes the ball 4.20 seconds to reach the base of the cliff. (a) How much is the initial speed vo? (b) What is its speed just before hitting the base of the cliff? (c) What is the total distance traveled by the ball?A basketball referee tosses the ball straight up for the starting tip-off. At what velocity (in m/s) must a basketball player leave the ground to rise 1.18 m above the floor in an attempt to get the ball?
- A tiger leaps horizontally from a 8.0m high rock and lands 9.5m from the base. What is her initial speed?A soccer ball is kicked horizontally off a cliff with an initial speed of 8 m/s and lands 16 m from the base ofthe cliff. What is the height of the cliff?The figure here shows the speed v versus height y of a ball tossed directly upward, along a y axis. Distance d is 0.37 m. The speed at height yA is vA. The speed at height yB is vA/3. What is speed vA?
- Water drops fall from the edge of a roof at a steady rate. A fifth drop starts to fall just as the first drop hits the ground. At this instant, the second and third drops are exactly at the bottom and top edges of a 1.25-m-tall window. How high is the edge of the roof?If the velocity of an object is given by V = 9* t4+2 - 1*t4 +7, when x0 = 4, what is its displacement after 6 seconds?A baseball is hit almost straight up into the air with a speed of 24 m/s . Estimate how long it is in the air. Express your answer to three significant figures and include the appropriate units.
- Ex. 2. A car driver in northern Ontario makes the following displacements: Ad₁= 15.0 km [W 30.0°N] Ad2 = 10.0 km [W 75.0°N] Ad3= 10.0 km [E 70.0° N] The trip takes 0.50 h. Calculate the average velocity of the car and driver in km/h.A basketball referee tosses the ball straight up for the starting tip-off. At what velocity (in m/s) must a basketball player leave the ground to rise 1.22 m above the floor in an attempt to get the ball?A helicopter is ascending vertically with a speed of 5.21 m/sm/s . At a height of 102 mm above the Earth, a package is dropped from the helicopter. How much time does it take for the package to reach the ground? [Hint: What is v0v0 for the package?] Express your answer to three significant figures and include the appropriate units.
