A ball is projected at an angle of elevation of 60 ° with an initial velocity of 120m/s. calculate 1) The time taken to get to the maximum height
ii) the time of flight

Explanation:

It is given that,

The angle of projection is 60 degrees

Initial velocity of the ball is 120 m/s

We need to find the time taken to get to the maximum height and the time of flight.

Time taken to reach the maximum height is given by :

g is acceleration due to gravity

(ii) Time of flight,

So,

Hence, this is the required solution.

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.

i believe the answer is a hope it and is correct
