The uniform thin pole has a weight of 30 lb and a length of 26 ft. the coefficient of static friction is μs = 0.3. if it is placed against the smooth wall and on the rough floor in the position d = 10 ft, will it remain in this position when it is released? (f

prolly a beacuse the momentuem the car has increases while going down hill

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

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
