During a fireworks display, a shell is shot into the air with an initial speed of 70 m/s at an angle of 65 degrees above the horizontal. What is the initial velocity of the firework shell in the x-direction?

What is the initial velocity of the firework shell in the y-direction?

What is the maximum height of the firework shell?

What is the range of the shell?

How long is the shell in the air?

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
