The impulse provided to the ball by the pitcher is equal to that provided by the catcher. In scenario 2, the objects do not stick together after the collision. n point B positive or. Answer: Remember that velocity is a vector and changes as the direction changes! In Experiment 2, the object is pulled along a horizontal surface with a spring scale such that the force reading on the spring scale remains constant while a motion detector is used to measure the instantaneous speed of the object as it is pulled. B. During an experiment, a toy car accelerates forward for a total time of 5s. Use K=1/2 mv2K=1/2mv2 with the block's initial speed for one trial because the initial speed is the same in all trials. C. The normal force for the riders is greater than the weight of the riders, mg. D. The normal force for the riders is smaller in magnitude than their weight, mg. Answer: If you draw a free-body diagram for the riders at "a", you would have a shorter arrow pointing up representing the normal force (what they THINK they weigh) and a longer arrow pointing down representing the weight (mg) of the riders.
