Use the exact values you enter to make later calculations. You repeat the same experiment that you did in the lab with the force table using two 100 g masses at 115º and 245° (a) Complete the table below. Force Mass (kg) Magnitude of Force (N) Angle (degrees) Ax (N) Ay (N)F1 0.100 115 F2 0.100 245 (b) Determine (by calculation) the value of F3 needed to balance the two forces Fi and F2. F3x = F3y = magnitude F3 = direction 03 =

sorry I don't know but I hope you get a answer soon

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
