A 25 kg object moving with a velocity of 3 m/s to the right collides with a 15 kg object moving to the left at 6 m/s. Find the velocity of the 25 kg object after the collision, if the 15 kg object continues to move to the left but at only 0.30 m/s

b.transmitters send radio waves, and receivers capture radio waves.

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
