At one instant a bicyclist is 40.0m due east of a park's flagpole, going due south with a speed of 10.0m/s. Then 30.0s later, the cyclist is 40.0m due north of the flagpole, going due east with a speed of 10.0 m/s. For the cyclist in the 30.0s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and(d) direction of the average velocity and the (e) magnitude and (f) direction of the average acceleration?
At one instant a bicyclist is 55 m due east of a park's flagpole, going due south with a speed of 19 m/s. Then, 24 s later, the cyclist is 75 m due north of the flagpole, going due east with a speed of 7 m/s. For the cyclist in this 24 s interval, find each of the following. (a) displacement magnitude m direction
At one instant a bicyclist is 60 m due east of a park’s flagpole, going south at 20 m/s. Then 30 s later, the cyclist is 40 m due north of the flagpole, going due east with a speed of 10 m/s. On an XY- coordinate system with the flagpole at the origin, for the cyclist in this 30 s time interval a) Draw the position and velocity vectors of the bicyclist as described. b) On your graph in part...

A particle's velocity is described by the function v_x=kt2, where v_x is in m/s, t is in s, and k is a constant. The particle's position at t_0=0s is x_0 = -6.00 m . At t_1 = 2.00 s , the particle is at x_1 = 8.40 m . Determine the value of the constant k.
A 321-kg boat is sailing 10.0° north of east at a speed of 2.00 m/s. 30.0 s later, it is sailing 33.0° north of east at a speed of 4.10 m/s. During this time, three forces act on the boat: a 32.3-N force directed 10.0° north of east (due to an auxiliary engine), a 23.9-N force directed 10.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...
