jeyben [28]

Answer:

Centripetal force acting on the body = 9.47 N

Explanation:

Mass of body, m = 2 kg

Radius, r = 3 m

It makes one revolution in 5 seconds.

Period, T = 5 s

$\texttt{Angular velocity, }\omega =\frac{2\pi }{T}=\frac{2\pi }{5}=1.256rad/s$

Centripetal force, F = mrω²

F = 2 x 3 x 1.256² = 9.47 N

Centripetal force acting on the body = 9.47 N

This grandfather clock, made entirely of Legos, has a 0.625 m long simple pendulum. What is the period of the pendulum? (include

PSYCHO15rus [73]

1. 1.59 s

The period of a pendulum is given by:

$T=2\pi \sqrt{\frac{L}{g}}$

where L is the length of the pendulum and g the gravitational acceleration.

In this problem,

L = 0.625 m

g = 9.81 m/s^2

Substituting into the equation, we find

$T=2\pi \sqrt{\frac{(0.625 m)}{9.81 m/s^2}}=1.59 s$

2. 54,340 oscillations

The total number of seconds in a day is given by:

$t=24 h \cdot 60 min/h \cdot 60 s/min =86,400 s$

So in order to find the number of oscillations of the pendulum in one day, we just need to divide the total number of seconds per day by the period of one oscillation:

$N=\frac{t}{T}=\frac{86,400 s}{1.59 s}=54,340$

3. 0.842 m

We want to increase the period of the pendulum by 16%, so the new period must be

$T'=T+0.16T=1.16 T = 1.16 (1.59 s)=1.84 s$

Now we can re-arrange the equation for the period of the pendulum, using T=1.84 s, to find the new length of the pendulum that is required to produce this value of the period:

$L=g(\frac{T}{2\pi})^2=(9.81 m/s^2)(\frac{1.84 s}{2\pi})^2=0.842 m$

Hatshy [7]

Answer:

The answer is (60 mph - 0 mph) / 8s = (26.8224 m/s - 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared.
