- If the rocket sled shown in the previous problem starts with only one rocket burning, what is the magnitude of this acceleration? Assume that the mass of the system is 2.10103kg , the thrust Tis 2.40104N , and the force of friction opposing the motion is 650.0 N. (b) Why is the acceleration n one-fourth of what it is with all rockets burning?(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) . The graphs in Figure 2.52 show plots of force versus acceleration for several objects. Rank these displays using the identifying numbers according to the mass of the affected object from smallest to largest. If any objects share the same mass, give them the same ranking. For reference, the graphs all have the same scale for their respective F and a axes. Explain your reasons for your rankings.How much time in seconds must a 270 N force from a catcher’s glove act to decelerate a fast ball (mass = 142 grams) to a complete stop if the ball was traveling at 90 miles per hour?
