maximum allowed value of the speed in roller coaster is given as

now from kinematics we can say

here initial speed will be

acceleration is due to gravity

now we can use this to find the height



so maximum allowed height will be 20.4 m
Given that force is applied at an angle of 30 degree below the horizontal
So let say force applied if F
now its two components are given as


Now the normal force on the block is given as



now the friction force on the cart is given as



now if cart moves with constant speed then net force on cart must be zero
so now we have




so the force must be 199.2 N
Answer:
<h3>What is the angular speed of the earth around the sun? </h3>
It takes the Earth approximately 23 hours, 56 minutes and 4.09 seconds to make one complete revolution (360 degrees). This length of time is known as a sidereal day. The Earth rotates at a moderate angular velocity of

<h3>
What is the tangential speed of the earth? </h3>
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
If you are charged to manage a project that aims to install wireless access points (aps) throughout the university campus, the steps to a foolproof plan for this project would be -
1. Recognize all of your network’s needs.
The most crucial step in any WiFi installation is probably knowing what your network needs are.
2. Select the appropriate hardware for your wireless network
Finding the ideal access point is much simpler if your needs are clear, but the wide range of options might be difficult.
3. Recognize your devices’ network restrictions.
It’s crucial to keep in mind that other factors besides your Internet connection and network hardware might affect how well your network performs.
4. Take into account the various cables you’ll need to use.
5. Consider how nearby interference may affect the installation of your wireless access point.
6. Decide where to put your wireless access point.
7. Analyze signal strength prior to making a decision.
