Suppose you have a 5,744 kg airplane whizzing around in a circle. Here is the top view of that plane. If the plane is travelling at 73 m/s and the radius of the circle is 2,618 m. What is the centripetal force in newtons on the plane?

Two masses are attracted by a gravitational force of 8.6 N. What will the force of attraction be if the distance between the two masses is quadrupled? (Round the final answer to four decimal places.) The force of attraction will be ____  N.

There is a car weighing 2,182 pounds sitting on a hill with an incline of 17°. How much weight needs to be applied to the car to keep it from rolling down the hill? Round your answer to the nearest hundredth of a pound

What is the centripetal acceleration of a plane traveling at 275 m/s around a circle of 5 m(5000m) ?

An object is moving in a circle of radius 2 m at a constant speed of 5 m/s. What is it's accelration?

The most recent Sirius XM satellite to provide radio music is called Sirius FM-6.  Launched in 2013, it has an orbital period of 1,436 minutes. What is the name of the force that provides the centripetal force keeping it in orbit?

Calculate the centripetal acceleration (in m/s2) of a  car traveling 20 m/s around a curved road with a radius of 10 m.

Consider a 2-kg ball on the end of a 1-m long cord whose mass is negligible. The ball is swung in a horizontal circle and makes 1 revolution per second. What is the centripetal acceleration of the ball?

A projectile is shot upward from the surface of Earth with an initial velocity of 99 meters per second. Use the position function below for free-falling objects. What is its velocity after 5 seconds? After 15 seconds? (Round your answers to one decimal place.) s(t) = -4.9t2 + Vot + So 5 s m/s 15 s m/s

Find a smooth surface that is positioned at an angle (a long board, a slide at a playground, a sloped driveway, etc.). Measure the distance from the starting point up the hill to the finishing point down the hill. Place a smooth running toy at the top of the hill, and let go. Measure the time it takes for the toy to roll down to the bottom of the hill. Repeat 4 more times. Use the middle of the 5 measurements for your calculations. Use the equation:                                                       a = g sin (q) to find the acceleration due to gravity. Off course you’ll need the equations of kinematics to determine the acceleration “a” first before finding g. Again compare your result to the actual value of 9.80 m/sec2 Then list 5 possible reasons why your result was different than the expected value. Data Time (in seconds) for 5 attempts: 3.5, 3.2, 3.8, 3.4, 3.7 Distance from starting point to end point: 9 feet Degree of the slide from which toy car rolls down: 45 degrees
