Golfer Arnold Hacker requires three putts from position A to put his ball in the hole. His first putt, from A to B, travels 8.0 m south. His second putt, from B to C, travels 1.2 m southwest. His third putt, from C to the hole at D, travels 0.50 m northwest. What would be the magnitude and direction of the single putt that would have put the ball into the hole, from A to D?​

b would be the answer

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
