QUESTION 5.6
What is the distance of the arc length in metres, when the radius of motion is 65.26 cm and the angle of rotation is 4.13 radians? Express your result with three digits of precision.
Suppose a rocks falls vertically off of a 1800 foot cliff. Use the distance equation for an object in free fall, d=16t2, to determine the rock's distance from the ground, in feet after 2 seconds of free fall. (Enter an exact number as an integer, fraction, or decimal).
An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled, in meters, before takeoff. (Answer in whole numbers, no decimals, no commas, no units. Ex: If your answer is 1,234 m, write 1234. Otherwise incorrect.)

- Read the question carefully and give me right solution according to the question. A particle travels around a circular path having a radius of 40 m. If it is initially traveling with a speed of 10 m/s and its speed then increases at a rate of (0.05 v) m/s 2, determine the magnitude of the particle’s acceleration at t = 3 s. Round your answer to 2 decimal places.arrow_forwardThe Bay of Fundy in Nova Scotia, Canada is reported to have the largest tides in the world with high tide and low tide occurring two times per day. The tides can measure over approximately 50.0 ft in height. At the Hopewell rocks at Hopewell cape, on a specific day height increase was recorded as a rate of 6.08 feet per hour. What is the rate in meters per second? Use Dimensional analysis to find answer.arrow_forwardYou hopefully used g=9.8 m/s2 (or thereabouts). That is the gravitational acceleration near the earth's surface. if you rise high above the earth, the gravitational acceleration decreases. Specifically, the gravitational acceleration is inversely proportional to the square of the distance from the earth's center. Equivalently, if you multiply the acceleration by the distance from the earth's center, you should get the same number for all heights. For this problem, take the radius of the earth as 3,902 miles, and calculate the gravitational acceleration of a satellite in low orbit, 182 miles above the surface.arrow_forward
