A particle's position along the x-axis is given by the equation; x(t) = 1t4 + 1t² +8 where x is in meters and t is in seconds. What is this particles average acceleration between t = 1s and t = 3s? Please express your answer with zero decimal places in units of m/s². Answer:
A bus initially at a bus stop accelerates continuously for a kilometer, taking a minute and a half. Upon closing in on the next stop, the driver then begins to hit the brakes until it reaches a full stop in 8 seconds. Find the total distance that the bus traveled and the velocity of the bus just before it begins decelerating.
A car starts from rest with an acceleration of 7.7 m/s² which decreases linearly with time to zero in 10.7 seconds, after which the car continues at a constant speed. Determine the time t required for the car to travel 560 m from the start. Answer: t = i S
During 9.85 s a motorcyclist changes his velocity from v1,x = -38.3m/s and v1,y = 11.7 m/s to v2,x = -21.5 m/s and v2,y = 28.1 m/s. Find the components of the motorcycles average acceleration during this process
A car accelerates at a constant rate from rest to 16 m/s in a distance of 74 m. What is the magnitude of its acceleration, in m/s2? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
A car begins at the position x1 = 6.0.m with an initial velocity of 20.4 m/s. If the acceleration of the car is 7.80 m/s^2 find the velocity of the car when it has reached the point x2 = 25.0m in m/s. Just input the number in the answer box, don't input units.
A car starts from rest with an acceleration of 5.7 m/s² which decreases linearly with time to zero in 8.2 seconds, after which the car continues at a constant speed. Determine the time t required for the car to travel 240 m from the start. Answer: t = i S
