Answer:
a) 15.49
b) Opposite to the ball's initial velocity
c) 258.16N
Explanation:
a)
b)
Since the player is kicking the ball in the opposite direction to which it came, the impulse is being directed opposite to the ball's initial velocity.
c)
Hope this helps!
Answer:
m1u1+m2u2=(m1+m2)v.
500×4+1500×2=(500+1500)V.
2000+3000=2000V.
5000=2000V.
V=2.5m/s
Answer:
140Ns
Explanation:
From Newton's 2nd law of motion
F = ma
F = m∆v/t
==> Ft = m∆v
impulse = Ft = 400 × 0.35 = 140Ns
Answer: Nothing they mind thier own business instead of being really noisy.
