A sodium ion (Na+) moves in the xy-plane with a speed of 2.70 ✕ 103 m/s. If a constant magnetic field is directed along the z-axis with a magnitude of 2.25 ✕ 10−5 T, find the magnitude of the magnetic force acting on the ion and the magnitude of the ion's acceleration. (a)
the magnitude (in N) of the magnetic force acting on the ion
N
(b)
the magnitude (in m/s2) of the ion's acceleration
m/s2

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

god i hope this !
