1.The graph in the figure shows the position of a particle as it travels along the x-axis. At what value of tis the speed of the particle equal to 0 m/s? A) 0 s B) 1 s C) 2 s D) 3 s E) 4 s 2.The motion of a particle is described in the velocity vs. time graph shown in the figure. Over the nine-second interval shown, we can say that the speedof the particle 3.An object is moving with constant non-zero velocity in the +xdirection. The position versus time graph of this object is
4.Ball A is dropped from the top of a building. One second later, ball B is dropped from the same building. Neglect air resistance. As time progresses, the difference in their speeds 5.The captain orders his starship to accelerate from rest at a rate of "1 g" (1 g= 9.8 m/s2). How many days does it take the starship to reach 10% the speed of light? (Light travels at 3.0 × 108m/s.) A)35 B) 70 C) 172 D) 365 6.A car is traveling due west at 20.0 m/s. If the acceleration of the car is a constant 1.0 m/s2due west, find the velocity of the car after 3.00 s. 7.A ball is thrown directly downward with an initial speed of 10.0 m/s from a height of 50.0 m. How much time does it take to reach the ground? 8.An object is thrown upward with a speed of 28.0 m/s. How long does it take to reach its maximum height? 9.If you coach special teams on a football team, you would want the punter to punt the ball such that the cover team can be at the receiver before he runs up field.
