Question

From the top of a tower of height 40m a ball is projected upward with a speedof 20m/sec at an elevation of 30 degrees . The ratio of the total time taken by the ball to hit the ground to its time of flight (time taken to come back to the point of projection) is? (g=10m/s)

Answer 1

Explanation:

h=40

theta=30

initial velocity= -20

g= 10

apply formula h= ut-1/2gt^2

learn direct formulas of such questions which will make u easy to do and if u do a question by having a mindset that it is difficult,you cannot do it. In physics, just apply that what you know ,if u don't know the formula read the questions and write every information given then think about the formula of the that chapter . believe me if u had taken physics , focus on numericals and write all formulas and learn as fast as you can . some people don't want to take physics but since it is a combination,they have to. but don't worry it's very easy believe me if u follow my points above.

Answer 2

Your answer is 2:1
