NEET · Physics · STD 11 - 3.2 motion in plane
A ball of mass \(1 \;kg\) is thrown vertically upwards and returns to the ground after \(3\; seconds\). Another ball, thrown at \(60^{\circ}\) with vertical also stays in air for the same time before it touches the ground. The ratio of the two heights are
- A \(1:2\)
- B \(1:1\)
- C \(2:1\)
- D \(1:3\)
Answer & Solution
