(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A car is driving through a rainstorm. Each raindrop of mass [tex]0.00005kg[/tex] hits the windscreen with velocity of [tex]16 ms^{-1}[/tex]. If [tex]500[/tex] raindrops hit the glass and run down the windscreen each second without bouncing, what force is exerted on the windscreen?

2. Relevant equations

Force = Mass x Acceleration

Momentum = Mass x Velocity

Inelastic Collisions:

[tex]m_1u_1 + m_2u_2 = (m_1+m_2)v[/tex]

3. The attempt at a solution

[tex]m = 5.0 \times 10^{-5}kg \ , \ u = 16ms^{-1}[/tex]

don't know how to start, need help!
