A shopping cart is pushed with 35 N of force to the right. It moved to the right 4m. What was the work done to the grocery cart.

Physics
1 answer:
Ratling [72]3 years ago
4 0

Answer:

140 N-m

Explanation:

Work done is equal to the product of force and displacement  

Here in this case,  

Force = weight of the cart

Displacement = distance moved by the cart

Work done = Force x displacement

= 35 N x 4 m

= 140 N-m

Motion with Constant Acceleration

Constant acceleration occurs when an object's velocity changes by an equal amount in every equal time period.

There are five frequently used formulas for motion in a straight line with constant acceleration. The formulas are given in terms of the initial velocity u, the final velocity v, the displacement (position) x, the acceleration a and the time elapsed t.

What happens to hydrogen in the core of stars
mezya [45]
Stars burn by fusing hydrogen into helium. The process can be observed as if hydrogen is a fuel for the star. Thanks to the process, the stars release heat and light. When there's no more hydrogen, the star starts to grow smaller while its heat increases. Eventually, the star dies.

A centrifuge rotor (hollow disk) is rotating at 10,000 rpm is shut off and brought to rest by a constant frictional torque of 1.
Y_Kistochka [10]

Answer:

The no of revolutions rotor turn before coming to rest is 1,601.1943 and time taken is equal to 19.21 seconds

Explanation:

here we know that torque = I×α

     α= angular acceleration

     I = moment of inertia of hollow disc = m×k^{2}

  given that m=4.37kg

                    k=0.0710m

           torque=1.2Nm

        w_{o}=10000\times \frac{\pi}{30} rad /s

         \alpha =\frac{torque}{I}

from the above equation we can calculate the angular acceleration of the hollow disc .

  since  w^{2}-w_o^{2} =2\alpha\theta

 from this above equation  \theta=\frac{w^{2}-w_{o}^{2}}{2\alpha }

   no of revolutions = \frac{\theta}{2\pi}  = 1,601.1943.

Now to calculate time we know that time = \frac{2\theta}{w+w_{o}}

   so upon calculating we will be getting t=19.21 seconds
