Velocity of Deidre and her dog is 2.11m/s.
<h3>What is velocity?</h3>
- Velocity is the rate of change of position of an object in a particular frame of reference
- Mathematically, velocity of an object = Displacement of the object/time taken
<h3>What is velocity of Deidre and her dog ?</h3>
- The distance covered by Deidre and her dog is 95 meter towards north.
- The time taken to cover the distance is 45 second.
- So velocity of Deidre and her dog =95/45
=2.11m/s
Thus , we can conclude that the velocity of Deidre and her dog is 2.11 m/s towards north .

The acceleration will be slower
Law of inertia
F=Ma 2 times slower
Answer:
A. 2.36 Newtons
Explanation:
F = GmM/d²
F = 6.673 x 10⁻¹¹(1)(5.98 x 10²⁴) / (1.3 x 10⁷)²
F = 2.36121...
