A sled with a mass of 25.0 kg rests on a horizontal sheet of essentially frictionless ice. It is attached by a 5.00-m rope to a
Tpy6a [65]

Answer:

The value is  F  =  34.3 \  N

Explanation:

From the question we are told that

    The mass of the shed is  m  =  25 \  kg

    The length of the rope is  l = 5.0 \  m

    The angular speed of the shed is w = 5 rev/minute = \frac{2* \pi * 5}{60 }= 0.524 \  rad/sec

Generally the force exerted on the shed is mathematically represented as

     F  =  m  *  w^2 *  l

=>  F  =  25  *  0.524^2 *  5

=>  F  =  34.3 \  N

A physical science test book has a mass of 2.2 kg. what is the weight on the Earth
Step2247 [10]

Weight = (mass) x (acceleration of gravity).

On Earth, acceleration of gravity = 9.8 m/s² (rounded)

On Earth, 2.2kg of mass weighs (2.2kg) x (9.8 m/s²) =

                                                             21.6 kg-m/s² = <em>21.6 Newtons</em>.

(That's about 4.85 pounds.)
