Answer:
60m/s
Explanation:
initial energy = final energy
g.p.e = k.e
k.e = 0.5 × mass × velocity²
g.p.e = 990000J as per Question
990000Nm = 0.5 × 550 × V²
V² = 3600
V = 60m/s
"Twice each second" means "2 per second". <em>Frequency = 2 Hz.</em>
<em>Period </em>= time for one bounce = <em>1 second</em>
Amplitude = distance between "not stretched" and "greatest stretch".
<em>Amplitude = 10 centimeters</em>
When 6210 bucks is converted to kilobucks, the result obtained is 6.21 kilobucks
<h3>Conversion scale </h3>
1000 bucks = 1 Kilobuck
Using the above convesion scale, we can express 6210 bucks in kilobucks
<h3>How to express bucks in kilobucks</h3>
1000 bucks = 1 Kilobuck
Therefore,
6210 bucks = (6210 × 1) / 1000
6210 bucks = 6.21 kilobucks
Thus, 6210 bucks is equivalent to 6.21 kilobucks

Answer:
17.54N in -x direction.
Explanation:
Amplitude (A) = 3.54m
Force constant (k) = 5N/m
Mass (m) = 2.13kg
Angular frequency ω = √(k/m)
ω = √(5/2.13)
ω = 1.53 rad/s
The force acting on the object F(t) = ?
F(t) = -mAω²cos(ωt)
F(t) = -2.13 * 3.54 * (1.53)² * cos (1.53 * 3.50)
F(t) = -17.65 * cos (5.355)
F(t) = -17.57N
The force is 17.57 in -x direction
