A huge cannon is assembled a planet that does not rotate. This planet has mass M and radius R. The cannon fires a projectile with mass m straight up at speed v0. The projectile goes so high that the acceleration of gravity at its peak is different from that at its launch point. What maximum height above the surface does the projectile reach, in terms of parameters defined in the problem, and physical or mathematical constants

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

the ima (higher than 1m) will be greater than the ima with the height of 1m.
