If the Earth was the size of a basketball, about 24 centimeters in diameter, about how thick is the Earth's crust? A. the thickness of the leather covering
B. the entire thickness of the ball's diameter
C. the thickness of the leather covering and another inch (or 2.5 centimeters) below that
D. 6 centimeters thick, or half the radius

are there options? cause you ain’t. real specific

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
