An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 3.5× 104 kg, and the force causes its speed to change from 7100 to 5400m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.8× 106 m determine the magnitude of the force.

Calculate the person's apparent weight at the bottom. c. suppose the ride is sped up to where the apparent weight at the top is zero. what would be the time for one revolution?

2-D star cluster puzzle Find the net gravitational force for III) Pentagon Let m=mass of the star = 1.99 x 10^30 kg, l=earth to star distance=149.6 x 10^6 km, G=6.67 x10^-11 N m^2/kg^2. Note that the masses of each star are the same. Also, it is advised to use vectors and components. And you can just find the gravitational net force of one of the stars in the shape
