A block of wood weighing 0.900 N rests on a table. A bullet weighing 0.100 N traveling with a velocity of 100 m/s hits the block of wood and sticks in it. The velocity of the bullet-block combination after the collision is 10 m/s. The coefficient of kinetic friction between the rough block and the table is 0.800. a) How far will the block slide before it skids to a stop?

Equation:

Ff = μ FN

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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
