according to PBS learning media on a roller coaster energy changes from potential to kinetic energy and back again many times over the course of a ride kinetic energy is energy that an object has as a result of its motion.

roller coaster system is greatest at the bottom of the largest downhill slope on the track typically at the bottom of the lift Hill

so at the bottom

A bicycle has a mass of 10kg and an acceleration of 2m/s². What is the net force of the bicycle?

kobusy [5.1K]

Answer:

<h3>The answer is 20 N</h3>

Explanation:

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

<h3>Force = mass × acceleration</h3>

From the question

mass = 10 kg

acceleration = 2 m/s²

We have

Force = 10 × 2

We have the final answer as

A cylindrical tank has a radius of 53 cm and a height of 1200 mm. It weighs 9.6 kN

xxTIMURxx [149]

Answer:

1985kg

Explanation:

assuming that

pi =3.14

oil density = 950kg/ cubic meter

g= 9.8m/s

$M=\frac{9600}{9.8 } + 950 * 3.14*.53^{2} *1.2=1985kg$

Determine the magnitude and direction of the resultant force of the following free body diagram.

Papessa [141]

Answer:

The magnitude and direction of the resultant force are approximately 599.923 newtons and 36.405°.

Explanation:

First, we must calculate the resultant force ( $\vec F$ ), in newtons, by vectorial sum:

$\vec F = [(-200\,N)\cdot \cos 60^{\circ}+(400\,N)\cdot \cos 45^{\circ}+300\,N]\,\hat{i} + [(200\,N)\cdot \sin 60^{\circ} + (400\,N)\cdot \sin 45^{\circ}-100\,N]\,\hat{j}$ (1)
