The three gures above represent the position, velocity, and acceleration vectors at time t = 0, of an object that experiences a constant net force. The gridlines represent 1m, 1%, and 1% for each of the gures, respectively. A graph of the y-component of a projectile's velocity is given from the time it is launched until right before it lands. The tick marks on the t-axis represent one second intervals. You may neglect air friction. ++ Two airplanes y between the same two cities. The destination city is due north of the origination, and both planes experience the same west-to-east crosswind, but travel at different airspeeds. Information An object moves in one dimension with the speed that varies according to the given formula. Let's dene positive velocity to mean the object is moving to the right, and negative velocity when the object is moving to the left. The quantities A and "I are constants. to) A + ((92 '0 Analysrs l. The velocity is not linear but quadratic as a function of time. This means that the acceleration will not be constant, and kinematic equations for constant acceleration will not apply for this motion. 2. We can solve for acceleration as a function of time by taking the derivative of the velocity function: (1.1} 2\
