The equations of motion of a projectile are given by x=36 t metre and 2 y=96 t-9.8 t^2 metre. The angle of projection is :
Options
- A⁻¹ ( 4 5 )
- B⁻¹ ( 3 5 )
- C⁻¹ ( 4 3 )
- D⁻¹ ( 3 4 )
Correct answer
A. ⁻¹ ( 4 5 )
Step-by-step solution
x=36 t metre 2 y= (96 t-9.8 t^2 ) metre Standard equations are, x=(u ) ty=u t- 1 2 g t^2u =36u = 96 2 =48 = u u = 48 36 = 4 3 = ⁻¹ 4 3 or = ⁻¹ 4 5
