Question

Two raindrops in a cloud collide perfectly inelastically. The first raindrop has a mass of 0.84 g and is travelling with $\vec{v_1} = (6.4 \hat{i} + 19.8 \hat{j})$ m/s. The second raindrop has a mass of 0.38 g and is travelling with $\vec{v_2} = (18.4 \hat{i} + 0.129 \hat{j})$ m/s. What is the resulting velocity of the combined raindrop? ? (a) $10.0 \hat{i} + 14.0 \hat{j}$ m/s ? (b) $7.5 \hat{i} + 10.0 \hat{j}$ m/s ? (c) $33.0 \hat{i} + 44.0 \hat{j}$ m/s ? (d) $-3.9 \hat{i} + 40.0 \hat{j}$ m/s ? (e) $-1.3 \hat{i} + 14.0 \hat{j}$ m/s ? (f) $15.0 \hat{i} + 20.0 \hat{j}$ m/s

Two raindrops in a cloud collide perfectly inelastically. The first raindrop has a mass of 0.84 g and is travelling with v⃗1⃗ = (6.4 î + 19.8 ĵ) m/s. The second raindrop has a mass of 0.38 g and is travelling with v⃗2⃗ = (18.4 î + 0.129 ĵ) m/s.
What is the resulting velocity of the combined raindrop?
? (a) 10.0 î + 14.0 ĵ m/s
? (b) 7.5 î + 10.0 ĵ m/s
? (c) 33.0 î + 44.0 ĵ m/s
? (d) -3.9 î + 40.0 ĵ m/s
? (e) -1.3 î + 14.0 ĵ m/s
? (f) 15.0 î + 20.0 ĵ m/s
