`        The celing of a long hall is 25m high.What is the maximum Horizontal distance that a ball thrown with a spEed  of 40m/s can go without hitting the ceiling of the ball?`
one year ago

```							Hello Rohith,That’s very simple if you know the concept of projectile motion and equations in kinematics.Just apply;  S=u X rootover(2h/g)                  [Speed=Distance/Time]Where rootover(2h/g) stands for time of flight;  S for Maximum horizantal distance; u for speed.Now put down the given values in the equation.S=40xrootover(2x25/10)S=40 rootover5.That’s your answer!Hope your query is cleared to a large extent.If you like the answer please approve it. Thank you, Your regards,Vidya Charan.

```							Hi Rohith,This is the case of a projectile motion First of all we have to find out the angle of projection.Using , h= u^2 (sinQ)^2 / 2g      here h= 25 m                g= 10 m/s^2              Solving this we get  sinQ = square root 5 / 4       By  this we can also find out cos Q  by right angle triangle law , which comes out to be = square root 11/ 4     The range of a projectile = 2 u^2 sinQ cosQ /g   Putting values  we get range as 20 × square root 55 Hope it helps you☺

```							GIVEN, h=25m ,u=40m/s g=10m/s ^2                                          H=u^2 sin^2theta /2g substitute the values.  You get the theta. Then find the value of R= u^2sin2theta/ g .Then you get the correct answer
