Initially, only the ball had momentum, an amount 5x5 = 25 in suitable units, ... 50kg moving at a speed of 0.5 meters per second, so the final momentum is 0.5x50 = 25 ... can imagine collisions in which the "total amount of motion", as defined above, ... the acceleration a of a body of mass m with an external force F acting on it

Explanation:

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
