Answer:
0.23 s
Explanation:
First of all, let's find the time constant of the circuit:

where
is the resistance
is the capacitance
Substituting,

The charge on a charging capacitor is given by
(1)
where
is the full charge
we want to find the time t at which the capacitor reaches 90% of the full charge, so the time t at which

Substituting this into eq.(1) we find

<span>Since the force is applied at an angle from the
horizontal, we will use the horizontal component of this force in calculating
for the displacements.
From derivation, the Fx is:</span>
Fx = F cos φ
Where:
Fx = is the horizontal component of the force
F = total force
φ =
angle in radian = 37 * pi / 180 = 0.645 rad
Calculating: Fx = 30.0 N * cos(0.645)
Fx = 23.97 N = 24 N
Calculating for Work: W = Fx * d
A. W = 24 N * 15 m = 360 N
B. W = 24 N * 16 m = 384 N
C. W = 24 N * 12 m = 288 N
D. W = 24 N * 14 m = 336 N
Answer:
a) 
b) 
Explanation:
From the question we are told that:
Height 
Bounce Height 
Generally the Kinematic equation is mathematically given by


Therefore Height


b)
Generally the Kinematic equation is mathematically given by




Explanation:
Period of a mass on a spring is:
T = 2π√(m/k)
T is a function of only m and k. So the period is independent of force.
