A man fire a bullet with a velocity of 500 m/s velocity upward.( use gravity 10m/s2.
calculate
A the maximum could the bullet rise
B THE VELOCITY OF THE BULLET AT t=10s ,20s and 60s
C. the time require to move up
D. the time of flight
E the height it rise at t=20s
F. the height it rise when first velocity equal to 40 m/s
