Answer: Got it!
Explanation: The water in a river flows uniformly at a constant speed of 2.50m/s between two parallel banks 80.0m apart. You are to deliver a package directly across the river, but you can only swim at 1.5m/s.

seconds
Explanation: apex verified
Answer:with the power of math and physic
Explanation:
Answer:
Explanation:
Given that,
Mass of astronaut
M = 62kg
Mass of wrench
m = 3.3kg
Speed at which wrench move away from the capsule
v = 20.5m/s
Speed of astronaut?
Let speed of astronaut be V
Since there is no external force, we would apply conservation of momentum
Momentum of the astronaut is equal to the momentum of the wrench
Momentum is given as
P = Mass × Velocity
P(astronaut) = P(wrench)
M×V = m×v
V = m×v/M
V = 3.3×20.5/62
V = 1.09 m/s
The astronaut speed is 1.09m/s
