Will Mark Brainliest Two descriptions about physical quantities are given below:
Quantity A: It is a force.
Quantity B: It changes when the object travels from Earth to Earth's moon.
What quantities are these most likely describing?
A: Both Quantity A and Quantity B are mass.
B: Both Quantity A and Quantity B are weight.
C: Quantity A is weight and Quantity B is mass.
D: Quantity A is mass and Quantity B is weight.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
