*hurry its for a quiz* a motorcycle and rider, having a total mass of 875 kg, are moving with a velocity of 15 m/s due east. what is the total momentum of the rider and cycle? a. 58 kg. m/s east b. 60 kg. m/s east c. 13.3 kg. m/s east d. 13,125 kg. m/s east

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
