1. 100 N
- 10 m/s^2
- 25 N towards her
- 25 N towards you
- 14.2 m/s^2
- 1 × 103 N
- friction between the tires and the road
5..0034g
- 2 × 105 m/s^2
- The same as a.
- 56 × 1022 N
- 2 × 10 −^7 N; very small force
8.g= 9 .8 m/s^2 ; you’ll get close to this number but not exactly due to some other small effects
- 2 × 10 −^7 N; very small force
- 4× 1026 N
- gravity
- 2× 1041 kg
9..006 m/s^2
1.. 765 - 4880 N
1.∼ 10 −^8 N very small force - Your pencil does not accelerate toward you because the frictional force on your pencil is much greater
than this force. - a. 4. 23 × 107 m b. 6. 6 Red. The same, the radius is independent of mass
- 9 × 107 m
- You get two answers forr, one is outside of the two stars one is between them, that’s the one you want,
- 32 × 1010 m from the larger star.

1.v=28 m/s
2.v−down,a−right - f−right
- Yes, 640N
