1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...
any help would be great! A car is moving along a straight road. At time t seconds, the position of the car (in feet) is s(t) = 51. Find the average velocity of the car over the time intervals given below. (a) t = 11 to t= 11.1 seconds (b) t = 11 tot = 11.01 seconds (c) t = 11 to t = 11.001 seconds (a) The average velocity of the car over the time interval from t =...
if we ignore air resistance, a falling body will fall 16t² feet in t seconds . estimate its instantaneous velocity at t = 7 using difference quotients with h = 0.1 , 0.01 and 0.001 . if necessary, round the difference quotients to no less than six decimal places and round your final answer to the nearest integer. Step 2 of 2: if we ignore air resistance, a falling body will fall 161 feet in seconds. Estimate its instantaneous velocity...
