An object with mass m = 0.56 kg is attached to a string of length r = 0.72 m and is rotating with an angular velocity ω = 1.155
Marta_Voda [28]

Answer:

The centripetal force is 0.54 N.

Explanation:

mass, m = 0.56 kg

radius, r = 0.72 m

angular speed, w = 1.155 rad/s

The centripetal force is given by

F = m r w^2\\\\F =0.56\times 0.72\times 1.155\times 1.155\\\\F = 0.54 N

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if
Ahat [919]

Explanation :

There are two types of collision i.e. elastic and elastic collision.

  • Elastic collision : In this type of collision, the total momentum and the kinetic energy of the particles remains constant.
  • Inelastic collision : In this type of collision, only the momentum remains constant while there is some loss of kinetic energy occurs.

From Newton's second law,

F = m a

a is the rate of change of velocity.

F=m\dfrac{v}{t}

There is a inverse relation between the force and the time of collision.

The change in <em><u>momentum</u></em> will remain the same during a collision, the force needed to bring an object to a stop can be <em><u>increased</u></em> if the time of the collision is <u><em>decreased</em></u>.

You apply a 150 N push on a frictionless sled over a period of 2 seconds. Show that the sled’s momentum changes by 300 kg·m/s.
Savatey [412]

Explanation:

Given parameters:

Force applied = 150N

Time  = 2s

Unknown:

Momentum change = ?

Solution:

The momentum change of a body is the difference between its initial and final momentum.

Momentum is the same as the impulse exerted on a body which is the product of force  and time

   Momentum = mass x velocity = force x time

The body initially at rest has a momentum of 0, as the momentum changes;

      Momentum change = Final momentum - initial momentum

                                         = f x t - (0)

                                         = (150 x 2) - 0

     Momentum change = 300kgm/s

Since the body is a frictionless surface, the net force is the same as the applied force.
