Use a graphing utility to obtain the path of a projectile launched from the ground (h = 0) at the specified values of θ = 35°, v0 = 300 feet per second. In the exercise, use the graph to determine the maximum height and the time at which the projectile reaches its maximum height. Also use the graph to determine the range of the projectile and the time it hits the ground. Round all answers to the nearest tenth.

A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, hh, in feet, tt seconds after it's shot is given by the equation: h=−16t2+146t+89h=-16t2+146t+89 Find the two points in time when the object is 126 feet above the ground (to one decimal places). Answer: The object is 126 feet off the ground at the following times:  (Enter your two answers separated by a comma. Round to ONE decimal places.)

Find the magnitudes of velocities vA and vB in the figure below, where, ? = 20.0° and vtot = 7.52 m/s.

A swimmer wants to cross a river that is flowing east at 0.95 m/s . To do so, the swimmer points  33.0o north of west. How fast must they swim relative to the water so that they swim directly north across the river? Give your answer in meters per second to two decimal places

The drawing shows two cars traveling in different directions with different speeds. Their velocities are: vAG = velocity of car A relative to the Ground = 32.4 m/s, due eastvBG = velocity of car B relative to the Ground = 21.0 m/s, due northThe driver of car B looks out the window and sees car A. What is the velocity (magnitude and direction) of car A as observed by the driver of car B? In other words, what is the velocity vAB of car A relative to car B?

An athlete performing a long jump leaves the ground at a 31.8 ∘∘ angle and lands 7.65 mm away.   What was the takeoff speed? Express your answer using three significant figures and include the appropriate units.

When describing motion, the origin can be placed arbitrarily to make the problem easier to understand and/or solv   True   False

What are the magnitude Δ? and angle ? of the change in velocity if the initial velocity is 15.0 m/s south and the final velocity is 70.0 m/s west? Let the angle ? be measured relative to the east direction (e.g., ?=90∘ means Δ? points north, ?=180∘ means Δ? points west, etc.).

the coordinates of an object moving in an xy plane vary with the time according to the eqations x=-7.85 sin w(omega)t, and y=4-7.85 cosw(omega)t. W(omega) is constant , x,y - in meters. And t in seconds.    Write expressions for the possition,velocity and acceleration vectors of the object at any time t>0.
