The average force exerted on the ball is 260 N away from wall. The ball velocity is much greater than that of the earth. The mass of the second sphere is 6.00 kg. The average force on the particle during the first 3 seconds is 2.67 N. 40. It takes the astronaut 240 seconds to reach his ship.
Friction accounts for the remainder.
The maximum compression of the spring is 0.21 m. 52. After 3 seconds the scale reads 23 N. 54. The coefficient of kinetic friction is 0.410. The 3m mass is scattered at an angle of 35.3 degrees.
