Answer: V = 6.97m/s
Step-by-step explanation:
Using equation of collision;
m1u1 + m2u2= v( m1 + m2)
V= m1u1 + m2u2/m1 + m2
Since the other object is moving in an opposite direction it momentum becomes negative
So we have
V=m1u1+(-m2u2)/m1 + m2
Impute the data
V = 17.3×8 + (-1.5×4)/17.5+1.5
V= 138.4 - 6/19
V= 132.4/19
V= 6.97m/s.
