Make a motion chart for a cannonball launched with an initial speed of 50m/s. Neglect drag and the initial height of the cannonball. After the ball lands on the ground enter zero for all speeds and heights if necessary. Use regular metric units (ie. meters). Round all speeds to nearest whole number, if necessary. |a| = unit t |v| unit unit unit 1 2 4. 5 7 10 direction of motion at 6s:

A small particle P starts from point O with a negligible speed and increases its speed to a value v = √2gy, where y is the vertical drop from O. When x = 46 ft, determine the n-component of acceleration of the particle. J Vertical Answer: an = i Horizontal ft ft/sec²

A golf ball is driven with the initial conditions shown in the figure. If the wind imparts a constant horizontal deceleration of 3.1 ft/sec², determine the values of r, r, r, 0, 0, and when t = 1.12 sec. Take the r-coordinate to be measured from the origin. Answers: r= ŕ= 7 = 0 = 0 = i Mo i i M 0 = i 0 103 mi/hr Too== = 30° ft x ft/sec ft/sec² rad/sec Wind rad/sec²

A rock is thrown out from the top of a 10 m tall building. The initial velocity and angle of the rock are 3 ?/? and 20° below horizontal.(a) What are the horzontal and vertical components of the rock’s initial velocity?(b) How long does it take the rock to hit the ground? (c) What is the horizontal distance, ?, traveled by the rock?

1.) Jason Renie set a world record of 77.0 m for motorcycle jump. Assume that he left the take-off ramp at 12.0° to the horizontal and that the take- off and landing heights are the same. Determine his take-off speed (in m/s). 2.) A model of a helicopter rotor has four blades, each 3.40 m long from the central shaft to the blade tip. The model is rotated in a wind tunnel at 550 rev/min. What is the radial acceleration (in m/s²) of the blade tip? 3.) A tourist in Cebu dives off a cliff with a running horizontal leap. What must her minimum horizontal speed (in m/s) be just as she leaves the cliff so that she will miss the ledge at the bottom, which is 1.75 m wide and 9.00m below the top of the cliff? 4.) In a test of a "g-suit", a volunteer is rotated in a horizontal circle of radius 7.0 m. What must the period (in s) of rotation be so that the centripetal acceleration has a magnitude of 3.0g? Note: Use 9.8 m/s² for the value of g. 5.) A pool ball leaves a 0.60-meter-high table with an…

A ball is thrown at 6.67 m/s at an angle of 32.0 degrees. How long (in seconds) will it take for the ball to reach it's maximum height? Tyno (Our oncwor

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.

Please do not reject this question I really need help with it. A) A distress rocket is launched from the top of a hill on the edge of the ocean. Its height above sea level, in meters, at time t, expressed in seconds, is represented by the function h(t) = -4.9t^2 + 16t + 200. I)What is the initial velocity of the distress rocket? II) What is its height at launch? III) How fast does the distress flare goes down, 6 seconds after being launched? B)With the function (shown in the image down below) II) Determine the slope of the tangent at the point whose abscissa is x = 2. II) Determines the equation of the tangent at the point whose abscissa is x = -3.
