26.  A football quarterback throws a 0.297kg football for a long pass. While in the motion of throwing, the quarterback moves the ball 2.478m, starting from rest, and completes the motion in 0.399s. Assuming the acceleration is constant, what force does the quarterback apply to the ball during the pass?Fthrow=       N*Round to the nearest thousandth if necessary.

Which of the following are true statements about velocity, acceleration, and force? (More than one answer) A   All three of these quantities are vectors. B   Force always causes velocity to increase. C   Acceleration always causes velocity to increase. D   Acceleration is a change in force per unit time. E   Force and acceleration are related by a law of nature; acceleration and change in velocity are related by a definition. F   Velocity is not a vector, but force and acceleration are vectors. G   Force = mass times velocity H   Acceleration and net force are always in the same direction, but velocity can be in any relative direction to those. I   Force and acceleration are related via mass.  J   Newton's Second Law of Motion says that: acceleration = mass times force

A physicist and a chemist are playing tug-of-war. certain length of time during the game, the partici- pants are essentially at rest. During this time, each person pulls on the rope (which can be treated as an ideal string) with a force of 350 N. What is the tension on the rope? For A. 700 N B. 350 N C. 175 N D. Other (specify) Ismbx

1. A person is pushing a 10.0 kg desk with a force of 17.0 N. If the friction opposing the motion was 2.0 N, what is the acceleration? 2. Given that the acceleration (from the 1st problem) was constant, if the person was moving the desk at 5.0 m/s at first and stopped after 20.0 seconds, what was his final velocity?
