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.
1) Personnel at an airport control tower track a UFO. At 11:02 a.m. it is located at a horizontal distance of 2.00 km in the direction 30⁰N of E at an altitude of 1200 m. At 11:15a.m. the location is 1.00 km at 45⁰ S of E at an altitude of 800 m. What was the displacement of the UFO? Express your result in component notation. Draw a picture graph

1. A rescue party for a missing child follows a search dog named Trooper. Trooper wanders around and makes trial sniffs along many different paths. Trooper eventually finds the child but his displacements on various legs seem to be truly convoluted. On one of the legs he walks 200.0 m southeast, and then he runs north some 300.0m. On the third leg, he examines the scents carefully for 50.0 m in the direction of 30 west of north On the fourth leg Trooper goes directly south for 80.0 m. picks up a fresh scent and turns 23 west of south for 150.0 m. Find the scalar components of Trooper's displacement vectors and his displacement vector for each leg.
