2.1 Vector 1. A particle starts from the origin at 1 = 0 with an velocity having an x-component of
25.0 ms and a y -component of - 10 ms. The partiele moves in an xy plane with an x
component of y acceleration only, given a, = 5.0 ms?
(a) determine the total velocity vector at any time.
(b) calculate the velocity and speed of the particles at I = 15.0 seconds
(c) determine the angle that makes with the x-axis at 5.0 seconds.
(d) evaluate the speed of the particle as the magnitude of the final velocity,​
