When an object is shot from the bottom of a long smooth inclined plane kept at an angle 60 ° with horizontal, it can travel a distance x 1 along the plane. But, when the inclination is decreased to 30 ° and the same object is shot with the same velocity, it can travel x 2 distance. Then x 1 : x 2…

Question

When an object is shot from the bottom of a long smooth inclined plane kept at an angle 60 ° with horizontal, it can travel a distance x 1 along the plane. But, when the inclination is decreased to 30 ° and the same object is shot with the same velocity, it can travel x 2 distance. Then x 1 : x 2 will be

Aicharya · Accepted Answer

The equation of motion in exclusive v 2 = 2 g sin 60 ° x 1 … ( 1 ) v 2 = 2 g sin 30 ° x 2 Equating, 2 g sin 60 ° x 1 = 2 g sin 30 ° x 2 x 1 : x 2 = 1 : 3
