Question

A particle moves on the xy plane, starting from the origin at t = 0 with an initial velocity having an x component of 20 m/s and a y component of -15 m/s. The particle experiences an acceleration that is in the x direction given by ax = 4.0 m/s2. a) Determine the total velocity vector at any time. b) Calculate the velocity and speed of the particle at t = 5.0 s and the angle the velocity vector makes with the x-axis. c) Determine the x and y coordinates of the particle at any time t and its position vector at this time.

Explanation / Answer

a) (20 +4t )i-15j
