Answer:
The change is momentum is given by ∆p=p(inital) - p(final) =4-2=2 kg.m/s
Explanation:
momentum is the product of mass and velocity (speed)
So it's initial momentum would be:
p=mv=(1)(4)=4 kg.m/s
It's final momentum is given by:
p=mv=(1)(2)=2 kg.m/s
Answer:
A) 6N
Explanation:
the weight of the astronaut on earth can be calculated with the formula
Weight = mass * gravity of earth
Since the gravitational force is one-hundredth of Earth, the formula should be
Weight = mass * (gravity of earth / 100)
Weight = (mass * gravity of earth) / 100
Since you already know the weight, you only need to divide by 100
Weight = (mass * gravity of earth) / 100
Weight = 600N / 100
Weight = 6N
