<u>Answer:</u>
Force = 20N
acceleration (a) = 1.5 m/s²
Mass of object (m) = ?
<u>From Newtons II law</u>
<em> F = m. a N</em>
m = F/a
m = 20/1.5
<em> m = 13.34 Kg</em>
<em>Mass of an object is 13.34 Kg</em>
Answer:
delta r(x) = (delta (r)) * cos(alpha), delta r(y) = (delta(r)) * sin(alpha)
Explanation:
Well it's a simple rule I guess...
