For an object moving in a path that's a circle or a part of one,
the centripetal force acts in the direction toward the center of
the circle.  That direction is perpendicular to the way the object
is moving.

A ski tow operates on a slope of angle 15.6 ∘ of length 340 m . The rope moves at a speed of 12.7 km/h and provides power for 53
GREYUIT [131]

Answer:

P = 34034.2 Watt

Explanation:

As we know that the slope angle is given as

\theta = 15.6^0

now the weight of the rider along the slope is given as

W = mgsin\theta

W = 69(9.81)sin15.6

W = 182 N

now total weight of all 53 riders along the slope is given as

F = 53 W

F = 9647.5 N

now the speed of the rope is given as

v = 12.7 km/h = 3.53 m/s

now the power required is given as

P = F.v

P = 9647.5(3.53)

P = 34034.2 Watt

On a road trip, a driver achieved an average speed of (48.0+A) km/h for the first 86.0 km and an average speed of (43.0-B) km/h
Bond [772]
A = 15, B = 1
48 + 15 = 63 for the first 86km
43 - 1 = 42 for the remaining 54 km
time = distance/speed
t1 = 86/63 = 1.3651hours
t2 = 54/42 = 1.2857hours
speed = distance/time
s = 140/2.6508
average speed = 52.8km/h

An object on a spring whose constant is 30. N/m
MrRa [10]

The mass of the object is 0.0076 kg

Explanation:

The frequency of a mass-spring system (simple harmonic motion) is given by

f=\frac{1}{2\pi}\sqrt{\frac{k}{m}}

where

f is the frequency

k is the spring constant

m is the mass

For the mass-spring system in this problem, we know:

k = 30 N/m is the spring constant

f = 10 Hz is the frequency

Solving the equation for m, we find the mass:

m=\frac{k}{(2\pi f)^2}=\frac{30}{(2\pi (10))^2}=0.0076 kg
