From the law of conservation of momentum
m1u1+ m2u2= m1v1+ m2v2
110*8+ 110*-10= 110*-10 + 110* v2
v2= 8 m/sec
Answer:
b because we apply Hooke's law
Explanation:
Hooke's law
Answer:
F = 33.12 N
Explanation:
given,
first force = 15 N is oriented at 58.0° counterclockwise
second force = (−19.0 N,18.5 N)
x-component of first force = 15 cos 58.0° = 7.95 N
y-component of second force = 15 sin 58.0° = 12.72 N
second component
now,
F netx = 7.95 - 19 = -11.05 N
F nety = 12.72 + 18.5 = 31.22 N
F = 33.12 N
θ = -70.51°
