Answer:
After 1.938 sec velocity of rock will be 36 m/sec
Explanation:
We have given initial velocity at which rock is thrown u = 55 m/sec
Final velocity v = 36 m/sec
Acceleration due to gravity
According to first equation of motion we know that , here v is final velocity, u is initial velocity, g is acceleration due to gravity and t is time
So ( Negative sign is due to rock is thrown upward )
So
t = 1.938 sec
So after 1.938 sec velocity of rock will be 36 m/sec
