Aunt Jane weights 45 Newtons. What is her mass?
RUDIKE [14]

Answer:

10.116 Pounds/45 newtons = 10.1164024 pounds/force

Explanation:

Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter. For our example, we will divide 10 N by 2 m/s/s, which give us a mass of 5 kg

An object moving in a straight line is decelerating. Which about its acceleration is necessarily true?
Varvara68 [4.7K]

Answer:

Its acceleration is certainly negative.

Explanation:

  • When an object moving in a straight line decelerates then its velocity certainly decreases.
  • Its acceleration is certainly negative.
  • As we know that acceleration is the rate of change in velocity and the object is decelerating i.e. its velocity is reducing with time.

a=\frac{v_f-v_i}{t_f-t_i}

where:

v_f\ \&\ v_i are final and initial velocities of the object

t_f\ \&\ t_i are final and initial time of observation.

  • Its SI unit is m.s^{{-2}
