Four containers A, B, C, and D contain tar. The tar in each of the containers A, B, C, and D have temperature of 100°C 200C 50°C and 25°C respectively which statement is true

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

f is prop to m1xm2 double m1 double force

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
