Question

When the Sun, directly overhead, a hawk dives toward the ground with a constant velocity of 4.35 m/s at 56.0degree below the horizontal. Calculate the speed of her shadow on the level ground. your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully, m/s A golf ball is hit off a tee at the edge of a cliff, its x and y coordinates as functions of time are given by x = 17.8t and y = 3.92t - 5.05t2, where x and y are in meters and t is in seconds, Write a vector expression for the ball's position as a function of time, using the unit vectors and .(Give the answer in terms of t.) rrightarrow = By taking derivatives, do the following. (Give the answers in terms of t.) obtain the expression for the velocity vector vrightarrow as a function of time vrightarrow =

Explanation / Answer

nothing but the horizontal component v= 4.3 sin 56 =3.565 m/s a) 17.8t i +(3.92t-5.05t^2)j b)17.8 i +(3.9-10.1t)j
