At t = 2.00 s, the particle's velocity is = (7.00 i + 8.20 j) m/s. (Use the following as necessary: t. Round your coefficients to two decimal places.)"

After a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by v=1.2i9.8tj where v is in meters per second and t is in seconds. The balls displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by r=00.3803vdt To perform the integral, you can use the calculus theorem [A+Bf(x)]dx=Adx+Bf(x)dx You can think of the units and unit vectors as constants, represented by A and B. Perform the integration to calculate the displacement of the ball from the edge of the table at 0.380 s.

A woman stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 21.5 m/s. The stone leaves her hand at a height of h = 57.0 m above level ground at the bottom of the cliff, as shown in the figure. Note the coordinate system in the figure, where the origin is at the bottom of the cliff, directly below where the stone leaves the hand. Write the equations for the position of the stone with time, using the coordinates in the figure. Use the following as necessary: t. Assume that x and y are in meters and t is in seconds.
