An object moves with constant acceleration. At t = 2.50 s, the position of the object is x = 2.00 m and its velocity is v = 4.50 m/s. At t = 7.00 s, v = -12.0 m/s. Find: (a) the position and the velocity at t = 0; (b) the average speed from 2.50 s to 7.00 s, and (c) the average velocity from 2.50 s to 7.00 s.
4. A particle starts from an initial position with coordinates To = 8 + 5ſm, at time t= 0, with a velocity of V. = 3i-8 m/s. The particle moves in the r-y plane with a constant acceleration, à = -21 - m/s. (a) At the instant the y-coordinate of the particle's position is -10 m, find the x- coordinate of its position. (b) Calculate the x- and y-components of the particle's position when the particle reaches its turning point...
12. A rubber ducky (located atx = 0 m) floats on a lake and bobs up and down due to one dimensional water waves Shown are a y() graph that depicts the vertical displacement of rubber ducky as a function of time and a y(x) graph that depicts the water wave as a function of position at the time t = 0 s What is the velocity of this water wave (both speed and direction)? y (in cm) at x...
A turtle ambles leisurely, as turtles tend to do, when it moves from a location with position vector 1x = 1.13 m and ny = -2.31 m in a lettuce garden to another location, with position vector r2.x = 3.35 m and r2.y = -4.41 m, where the lettuce appears to be tastier (but really is not; this turtle cannot see very well). The excursion takes 335 s to complete. What are the components and the magnitude of the turtle's...
