Decreasing the mass or the speed of the cart? HELP QUICK Question 1 options:
Kinetic energy is least as you are moving past the bottom of the swing and going back up to the highest point

Kinetic energy is least at the lowest point of your swing when you are closest to the ground

Kinetic energy is the least when you are halfway between the highest point of the swing and the bottom

Kinetic energy is least at the at the top of the swing when you are still for a moment just before falling again

Kinetic energy is least at the at the top of the swing when you are still for a moment just before falling again

Explanation:

B: Kinetic energy is the least when you are halfway between the highest point of the swing and the bottom

Explanation:

This is the answer

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

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
