Even though Alice visits the wishing well frequently and always tosses in a coin for good luck, none of her wishes have come true. As a result, she decides to change her strategy and make a more emphatic statement by throwing the coin downward into the well. If the water is 5.63 m below the point of release and she hears the splash 0.93 seconds later, determine the initial speed at which she threw the coin. (Take the speed of sound to be 343 m/s.)

A biologist studying the motion of bacteria notes a bacterium at position r 1=2.2i + 3.7j − 1.2k μm (1μm = 10-6). After 7.2 seconds the bacterium is at r2 = 4.6i + 1.9k μm. Given that the acerage velocity is equal to 0.33i - 0.51j + 0.42k. Calculate the magnitude of the average velocity.
The Sultan Qaboos road is designed to operate at a speed of 100Kmph, but some people are racing above the limit and some people are trailing below 80Kmph, and cause multiple incidents on road. Design a radar frequency so that detect the both the speeds that is below 70kmph, and above 110kmph, provided the PRF is 500Hz only. The radar should not be blind between the above specified velocities and it should detect both the speed accurately.(Explain your assumptions of the radar and their specifications clearly, so that which radar frequency can be readily used on site)
Consider the motion described by the figure below. (a) Find the displacement at t = 12.4 s(b) Find the displacement at t = 12.9 s(c) Find the displacement at t = 16.5 s
A car was parked on the side of a hillside road at the top of a hill. Unbeknown to the owner, its parking brake failed and a tremor from nearby construction set it in motion with negligible initial speed down the hill. Assume the acceleration was constant down the hill, the car was given a speed ticket by a traffic camera at the foot of the hill, which measured the speed of the car at 22.0 m/s. The video recording showed the car took 34.0 seconds to slide down the hill. How long is the road on the side of the hill? need 3 sig figs
