Question

it football player kicks a ball of an angle of 34to the horizontal with an initiedo speed 15ms. Assuming that the ball travels in a Vertical plane calculate (6) the time at which the hall Lii) the morninum hegeld sloocheed (tri) the Persientel 10) the time for which the ball is in a air​

Answer 1

Answer:

Angle of projection θ=300

initial velocity, μ=15 m/sec

a) Maximum height =2gμ2sin2θ

                                 =2×9.8(15)2×sin2300

                                 =2.869 m

b) Time of flight for projectile =g2μsinθ

                                                 =9.82×15×sin300

                                                 =1.53 sec

c) Range =gμ2sin2θ

                =9.8(15)2×sin600=9.8225×23

                =19.74 m
