Question

4.
A particle moves in the xy plane, starting
from the origin at t=0 with an initial
velocity having an x component of
20 ms and a y component of - 15 ms. The
particle experiences an acceleration in the
x direction, given by a = 4 ms-?. Determine
the total velocity vector at any time.
(A) V = (10 +6t) i-150 į
(B) Vr = (20 + 4t) î–150)
(C) va = (20 + 4t) i-15
(D) v = (5 +6t) î–159​

Answer 1

Answer:

c

Explanation:

v=u+at

given ax=4 ux=20

total velocity =(20+4t)i-15j
