What happens to a shopping cart if you get it rolling and then release it?

Physics
1 answer:
Anit [1.1K]3 years ago
7 0

Answer:

It will slowly come to a stop as long as it is moving on a flat surface

Explanation:

If the cart is moving on a flat surface, it will slowly come to a stop due to the friction forces acting on its wheels.

If the cart is on an inclined surface, it may gain acceleration enough to overcome any friction force, and thus continue with an accelerated motion.

oee [108]
It's called an action plan

As long as we could organize what actions that are going to be taken, when, where, and what could we achieve by that action, basically we can use anything as an action plan

Action plan is different from a to - do list because an action plan is goal oriented. As long as the goal already accomplished, we don't necessarily have to follow the remaining steps

In an arcade game a 0.099 kg disk is shot across a frictionless horizontal surface by compressing it against a spring and releas
Sonja [21]

Answer:

The speed of disk is 1.98 \frac{m}{s}

Explanation:

Given:

Mass of m = 0.099 kg

Spring constant k = 244 \frac{N}{m}

Compression of spring x = 4 \times 10^{-2} m

From energy conservation theorem,

Spring potential energy converted into kinetic energy,

   \frac{1}{2} m v^{2} = \frac{1}{2} k x^{2}

  v = \sqrt{\frac{k x^{2} }{m} }

  v = \sqrt{\frac{244 \times 16 \times 10^{-4} }{0.099} }

  v = 1.98 \frac{m}{s}

Therefore, the speed of disk is 1.98 \frac{m}{s}

The unit for momentum is which of the following?
Alika [10]

(any unit of mass) x (any unit of speed)  is a unit of momentum.

The only choice on the list with the dimensions of (mass) x (speed)
is 'c'.

'a' is a unit of force.
'b' is meaningless.
'c' is a false statement.

When a sound wave moves through a medium such as air, the motion of the molecules of the medium is in what direction (with respe
Alchen [17]

<span>A sound wave is a pressure wave that results from the vibration of the particles o the medium from the source. The motion of the particles in the medium is parallel to the direction of the energy transport. The type of wave formed by a sound wave is the longitudinal wave. </span>A longitudinal wave is characterized by rarefactions. A longitudinal wave is a wave motion wherein the particles in the wave medium are displaced parallel to transport. When motion is detected from the source, the particle next to it vibrates from its rest position and a progressive change in phase vibration is observed at each particle within that wave. The result is that the energy is transported from one region to the other. These combined motions result in the movement of alternating regions of rarefaction in the direction of propagation.

Salt Flats of Utah, had a mass of 4100 kg, and its engine
Andrej [43]

Answer:

<h2>16.59 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{68000}{4100}  =  \frac{680}{41}  \\  = 16.58536

We have the final answer as

<h3>16.59 m/s²</h3>

Hope this helps you
