A famous golfer strikes a golf ball on the ground, giving it an initial velocity v = v0xi + v0yj. Assume the ball moves without air resistance and its motion is described using a Cartesian coordinate system with its origin located at the ball's initial position. show answer No Attempt 25% Part (a) Determine the vertical component of the initial velocity, v0y, assuming the ball reaches a maximum height of 28 during the drive. Give your result in m/s.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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

not too sure thinking all accelerations are pointed down
