A bus with a vertical wind shield moves horizontally at a speed of 40km/hr, while rain is falling vertically at a speed of 30km/hr. The angle at which rain drops strike the wind shield is? |
Answer» ANSWER:θ = 53⁰ Explanation:Let angle θ at which RAIN drops strike the wind shield . GIVEN : Horizontal component of falling rain is 40 km / hr Vertical component is 30 km / hr . We know tan θ = Horizontal component / Vertical component tan θ = 40 km / hr / 30 km / hr . tan θ = 4 / 3 θ = tan⁻¹ ( 4 / 3 ) . θ = 53⁰ |
