The mass of the skydiver is 122.2 kg
Explanation:
We can solve the problem by using the concept of weight.
The weight of a body is the force of gravity acting on the body; near the Earth's surface, its magnitude is given by
where
m is the mass of the body
is the acceleration of gravity
In this problem, we know the weight of the skydiver:
W = 1198 N
So we can re-arrange the equation to find its mass:

Answer:
0.25m/s
Explanation:
Given parameters
m₁ = 5kg
v₁ = 1.0m/s
m₂ = 15kg
v₂ = 0m/s
Unknown:
velocity after collision = ?
Solution:
Momentum before collision and after collision will be the same. For inelastic collision;
m₁v₁ + m₂v₂ = v(m₁ + m₂)
Insert parameters and solve for v;
5 x 1 + 15 x 0 = v (5 + 15 )
5 = 20v
v = = 0.25m/s
