A soccer ball is kicked upward with an initial vertical component of velocity is 15 m/s, and an initial horizontal component of velocity is 5 m/s.
a) What is the angle that the ball was kicked? b) Sketch the trajectory of
the soccer ball. c) Neglecting wind resistance how long will it take for the
ball to reach the top of it's trajectory. d) What is the instantaneous
velocity of the ball at 2 seconds. Round answers to nearest tenth.

this is a good question! i'll do some research and come back when i have the answer!

and 1and 1

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
