a body is projected at an angle of 30 degree with a velocity of 9.8 metre per second when does it reach the maximum height |
|
Answer» The TIME taken to reach the MAXIMUM height is 0.5 secExplanation:GIVEN :A body is PROJECTED at an angle of 30° with a VELOCITY of 9.8 m/sTo find :the time taken to reach the maximum heightSolution : The time taken to reach the maximum height is given by, whereu denotes the velocity with which the body is projectedθ denotes the angle of projectiong denotes the acceleration due to gravityθ = 30°u = 9.8 m/sg = 9.8 m/s²Substitute the values, Therefore, the time taken to reach the maximum height is 0.5 sec____________________Know more :For an object projected at an angle θ with the horizontal, The maximum height is given by, The range is given by, |
