An object is launched at a velocity of 20 m/s in a direction making an angle of 30° upward with the horizontal. Calculate the
time to reach its maximum height. Use for gravity acceleration the value 10. Do not include units of measure in the result.
Sin30° = 0.5
Cos30° = 0.87
Expert Solution
Step 1
Given data
The velocity of the object launch is
The angle of the projectile is
The accleration due to gravity is
The time to reach the maximum height is half of the total time of flight.
The time of flight is,
