1.The graph in the figure shows the position of a particle as it travels along thex-axis.At what value oftis the speed of the particle equal to 0 m/s?A) 0 sB) 1 sC) 2 sD) 3 sE) 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 thespeedof the particle
3.An object is moving with constant non-zero velocity in the +xdirection.The positionversus time graph of this object is
4.Ball A is dropped from the top of a building.One second later, ball B is dropped fromthe same building. Neglect air resistance.As time progresses, the difference in theirspeeds2
5.The captain orders his starship to accelerate from rest at a rate of "1g" (1g= 9.8 m/sHow many days does it take the starship to reach 10% the speed of light? (Light travels at3.0 × 108m/s.)).A)35B) 70C) 172D) 3656.A car is traveling due west at 20.0 m/s. If the acceleration of the car is a constant 1.0 m/s2
due 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 of50.0 m. How much time does it take to reach the ground?
