Asked by Rita
an anti aircraft shell is fired vertically upward with a muzzle velocity of 200 m/sec. Compute theinstantaneous velocities at the ends of 30 & 50 seconds.

At t=30s, the velocity would be
V = 200 - 30g = -94 m/s
It will be on the way back down but will not have hit the ground yet.
At t = 50 s, V = 200 - 490 = -290 m/s
but it will have hit the ground before that, when V = -200 m/s.
Are you sure the muzzle velocity was not higher than 200 m/s? A typical value is 1000m/s
V = 200 - 30g = -94 m/s
