Question

A particle leaves the origin with initial velocity v⃗ o=8.0i^+15j^m/s, undergoing constant acceleration a⃗ =−1.5i^+0.25j^m/s2.

In what direction is it moving counterclockwise from the positive x-axis ?

Answer 1

Answer #1

From

X=V_oxt+(1/2)at²

=>0 =8t +(1/2)(-1.5)t²

16=1.5t

t=10.67 s

From

m/s

Direction

Counterclock wise from +x-axis
