Determine the kinetic energy of a 1000kg rollercoaster car that is moving with a speed of 20.0 m/s
stich3 [128]
KE = 1/2mv^2
KE = 1/2(1000)(20^2)
KE = 2.0 * 10^5 
or 
KE = 200,000

hope this helps :)

A very long straight current-carrying wire produces a magnetic field of 20 mt at a distance d from the wire. to measure a field
padilas [110]

The distance covered is 4d.

<h3>What is the distance?</h3>
  • Distance is a measure of how far apart two objects or locations are using numbers.
  • The distance can refer to a physical length or an estimate based on other factors in both daily language and physics (e.g. "two counties over").
  • The terms "distance from A to B" and "distance from B to A" are frequently used interchangeably.
  • A distance function or metric is a technique to describe what it means for components of space to be "near to" or "far away" from each other in mathematics.
  • It is a generalization of the idea of physical distance. Distance is a non-numerical unit of measurement in psychology and the social sciences; psychological distance is the separation of an object from itself along dimensions including time, space, and isolation.

We know that

the magnetic field is inversely proportional to distance.

\dfrac{B_1}{B_2} = \dfrac{D_2}{D_1}

\dfrac{20}{5} = \dfrac{D_2}{d}

D_2 = 4d

A 2.4 m long rod of mass m1 = 14 kg, is supported on a knife edge at its midpoint. A ball of clay of mass m2 = 3.5 kg is dropped
Mashutka [201]

Explanation:

It is known that;

            L_{i} = L_{f}

Now, we need to calculate the value of L, that is, angular momentum.

Therefore,

                   L= mvr

where,   m = mass

              v = velocity

              r = radius

Hence,

               L = m(\sqrt{2gh}) \times r

So,

              L = (2.2 \times (\sqrt{2 \times 9.81 \times 1.4}) \times 0.9)

                  = 10.37 Js

Thus, we can conclude that angular momentum of the rod and clay system about the point of support immediately after the inelastic collision is 10.37 Js.

What does newtons second law of motion state about an objects acceleration
vagabundo [1.1K]
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
