Answer:
The wave speed in SI units, is closest to - 2.7 m/s
Explanation:
given information:
y = 0.005 cos [π(38t - 14x)]
we know that the wave function is
y = A cos (kx ± ωt)
where
A = amplitude
w = angular velocity
k = wave number
thus,
y = 0.005 cos [(14πx - 38πt)]
ω = - 38π
k = 14π
to find the speed v, we use the equation below
v = ω/k
so,
v = - 38π/14π
= - 2.7 m/s
Answer:
28 m/s
Explanation:
v(final)^2=v(initial)^2+2a(delta y)
=sqrt(2*-9.8 m/s^2*-40)
28 m/s

Explanation:
I don't know more!
Explanation:
It’s b because a spring of negligible mass then if u multiply
I got you
Explanation:
normal force = 400 g cos 35
friction force up slope = .6 (400 g) cos 35
weight component down slope = 400 g sin 35
400 a = 400 g sin 35 - .6 (400 g cos 35)
a = g (sin 35 - .6 cos 35) = .082 g
I hope this helps you
