Here are three graphs of velocity plotted against time. Below there are several situations. For each situation select the appropriate velocity plot which represents the velocity over the time period mentioned. Each situtaion will state the direction of the axis (eg, choose the positive direction to be upward or choose the direction to the right) 20 A 15 20 25 Time 25 20 15 10 Time 10 10 Time A ball is tossed up into the air. Choose the positive direction upward. Which graph best represents the velocity from the time just after it leaves your hand to the time just before you catch it again? A car starts from rest at a traffic light and accelerates with constant acceleration in the Easterly direction for 5.0 seconds. Choose the East direction to be positive. Which graph best represents the velocity from the time the car is just starting up to the time it has traveled a certain time at constant acceleration? B You lean over the edge of a building and release a ball (it starts at rest). Choose the positive direction upward which graph best represents the velocity from the time ust after it leaves your hand to the time just before it hits the rocks below? t. Tries 3/10 Previous Tries

    The big deal with 2-dimensional kinematics is that we can break most problems back down into one dimensional problems if the acceleration is constant. For example, vx = vx0 + axt where vx0 is the x component of the velocity at time t=0s, vx is the x component of the velocity at time t, and ax is the x component of the acceleration. In the vertical direction, the same formula is valid for all of the y components: vy =...
