body thrown up along a frictionless inclined plane of angle of inclination 30∘ covers a distance of 40 m along the plane. If the body id projected with the same speed at an angle of 30∘ with the ground, it will have a range of
(Take g=10 ms−2) please explain it clearly😣😥😥
We found a similar question to the one that you posted. Please check it out here.
Let u be the initial speed with which the body is thrown along the inclined plane. As shown in the figure , the effective deceleration is given by
Now, from the third equation of motion,
A projectile projected at angle θ=30∘ with this speed will have a range of
Hence the correct choice is (c).
