Question 14 0 out of 1 points The mass of Earth is 5.98 x 1024 kg and the radius of Earth is 6400 km. What would be the gravitational force between the Earth and an asteroid of mass 2.2 x 105 kg when the asteroid is at distance 372953km from the Earth? (Hint: convert distance from km to m) Selected Answer: Correct Answer: 2.35611 610 a 10% Question 15 0 out of 1 points Two gliders of masses 0.545 kg and 0.536 kg moving from opposite directions collide on an air track. The initial speeds are 0.57 m/s and 0.41 ms, respectively. After the collision, the 0.545-kg glider rebounded with speed of 0.27. Assuming the first glider is initially heading in the positive direction, what is the velocity of the second glider after the collision (in m/s)? Include negative sign, IF appropriate.
