On a typical road, the force of friction during a turn can be up to 195,000 N. If a car has a mass of 1050kg and makes a turn with a radius of 20.0m, how fast can it be going?

The Earth’s radius is about 6370 km. An object that has a mass of 80kg is taken to a height of 200 km above the Earth’s surface. What isthe object’s mass at this height?

A car of mass 1,110 kg makes a circular turn of radius 16 m along a level roadway. The coefficient of friction is 0.822 between the tires and the road. How fast (in m/s) can the car go without skidding off the turn? (Use the approximation that g = 10 m/s²) Answer: m/s (round to the nearest hundredth)

A planet has a radius of 4.00 x 10^6 m, and rotates so rapidly that an object on the equator feels only 10% of the weight that it feels at the poles. What is the speed of an object at the equator?

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 5 x 1010 m (inside the orbit of Mercury), at which point its speed is 9.6 x 10* m/s. Its farthest distance from the Sun is beyond the orbit of Pluto. What is its speed when it is 6 x 1012 m from the Sun? (This is the approximate distance of Pluto from the Sun.) speed = m/s Additional Materials eBook O Show My Work (Optional)

A huge cannon is assembled on an airless planet having insignificant axial spin. The planet has a radius of 6 x 106 m and a mass of 4.68 x 1023 kg. The cannon fires a projectile straight up at 1,532 m/s. An observation satellite orbits the planet at a height of 953 km. What is the projectile's speed as it passes the satellite? [Hint: Be careful with units!] V= m/s

A rock is dropped from high above the surface of the Earth. The initial speed is 0, and the initial height above the surface is NXRE where RẺ is the radius of the Earth. Calculate the speed of the rock when it hits the upper atmosphere, say at height 20 km above the surface. DATA for the Earth: radius RE 6.38×106 m; mass ME N = 15; (in m/s) = = 5.98x1024 kg.

What’s the speed of a point on the equator of a planet whose radius is 2.2 times that of Earth?

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.6 x 1010 m (inside the orbit of Mercury), at which point its speed is 9.1 x 104 m/s. Its farthest distance from the Sun is far. beyond the orbit of Pluto. What is its speed when it is 6 x 1012 m from the Sun? (This is the approximate distance of Pluto from the Sun.) speed = m/s Enter a number. AdditionaI Matenais O eBook

An object on a certain planet has an escape speed of V. If another planet has twice the radius and twice the mass of the first planet, the escape speed will be?
