- A race car travels around the horizontal circular track that has a radius of 310.6m, If the car increases its speed at a constant rate of 6.09 m/s^2 starting from rest, determine the time needed for it to reach an acceleration of 8.49 m/s^2.If we apply the above equations to the case of an object that does not change its direction of travel as it moves with constant acceleration, we find that the object: Undergoes a displacement Ax = x- x, . Note that displacement is a positive quantity if x > x, and a negative quantity if x < x,. Has average velocity v = (x - x )/t = (v + vo)/2. Note that velocity has the same sign as displacement. Travels distance d = |Ax| = |x – x,| . Note that distance is always a positive quantity. Has average speed d/t . Note that speed is always a positive quantity. Has constant acceleration a = (v – vo)/t . Acceleration may be positive or negative, depending on how velocity changes. - Xo For the case of an object that does change its direction of travel as it moves with constant acceleration, which of the quantities listed above are different? Question(A A person walks first at a constant speed of 4.80 m/s along a straight line from point to point and then back along the line from B to A at a constant speed of 3.05 m/s What is her average velocity over the entire trip? B m/s
- A ball is thrown straight up with an initial speed of 15.5 m/s. At what height above its initial position will the ball have one‑half its initial speed? height: mA position function is given by F(t)= (10m+20t)i-5t²j. What is the velocity of the object it describes at t=2.0s? Using the same position function as the previous problem, what is the acceleration function? Using the same position function again, make an accurate plot of the object's trajectory over the first two seconds of flight. What's the lowest speed of the object in the prior problem in that time interval? IA bowling ball travelling with a constant velocity hits the pins at the end of a bowling lane 16.90m long. The bowler hears the ball hitting the pins 4.75s after the ball is released from his hands. What is the velocity of the ball? (speed of sound is 343 m/s) Playing jackstone as a kid, you discovered that there is a certain time before the rubber ball falls and you took advantage of this when picking up the stars on the floor. If you threw the ball 3.07m/s up into the air, how fast will it be moving at a height of 18.16cm? How much time has elapsed upon reaching this height? A skydiver jumped out of a plane to shoot a skydiving scene for a certain spy movie. At what point in time should this spy-wannabe open his parachute when he is aware that the plane was at the altitude of 4677.82m, and he needs to open it at a height of 431.36m?
