A particle thrown up vertically reaches its highest point in

Last updated: 7/27/2022

A particle thrown up vertically reaches its highest point in time t, and returns to the ground in a further time t₂. The air resistance exerts a constant force on the particle opposite to its direction of motion. Then (a) t₁ > t₂ (b) t₁ = t₂ (c) t₁ <t₂ (d) may be (a) or (c) depending on the ratio of the force of air resistance to the weight of the particle.
