Assume air resistance is negligible unless otherwise stated. Calculate the displacement in m and velocity in m/s at the following times for a rock thrown straight down with an initial velocity 11.4 m/s from the Verrazano Narrows bridge in New York City. The roadway of this bridge is 70.0 m above the water. (Enter the magnitudes.) (a) 0.500 s displacement velocity (b) 1.00 s displacement velocity (c) 1.50 s (e) displacement velocity (d) 2.00 s displacement velocity 2.50 s m m/s m m/s m m/s m m/s

A football is kicked from ground level with an initial velocity of 23.6 m/s at angle of 53.0° above the horizontal. How long, in seconds, is the football in the air before it hits the ground? Ignore air resistance. S

Find the following values for path B in Figure 3.22. All blocks are 120 m on a side. Start Figure 3.22. (a) the total distance traveled X m (b) the magnitude and direction of the displacement from start to finish ON of E w/

Problem 4 An object is launched at a velocity of 25 m/s in a direction making an angle of 20° upward with the horizontal. What is the maximum height reached by the object?

A particle at rest undergoes an acceleration of 2.1 m/s2 to the right and 3.9 m/s2 up. a)What is its speed after 5 s in m/s? b)What is its direction with respect to the horizontal at this time? Answer between −180◦ and +180◦.

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.).

A canon is elevated at an angle of 45.0°. It fires a ball with a speed of 352 m/s. Calculate the amount of time that the ball is in the air before it reaches the ground.

NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec.                                           Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.
