Answer:
Mass of raft=m1= 1000kg
Mass of paddle=m2=40kg
Speed of paddle=v2=3 m/s
Speed of raft=recoil speed=v1=?
Formula
V1= -(m2/m1)v2= -(40/1000)3= - 0.12m/s
Explanation:
Here the raft has much greater mass as compare the paddle and its velocity will always be negative due to recoil. 1 and 2 with masses and velocities are subscripts.
