Answer:
82.7 kg
Explanation:
the mass of the boxer remains unchanged, this is because mass is a measure of the quantity of matter in an object irrespective of its location and the gravitational force acting at its location. this means mass is independent of the gravitational acceleration hence it remains the same 82.7 kg. its unit is in kilograms (Kg).

Answer:
Explanation:
mass of baseball, m = 0.148 kg
initial velocity, u = 15.5 m/s
final velocity, v = 10.1 m/s
Impulse is defined as the change in momentum of the body.
Impulse = change in momentum
I = m (v - u)
I = 0.148 (10.1 - 15.5)
I = - 0.8 Ns
Answer:
A
Explanation:
the horizontal and vertical force acting on it consist a net force on the inclined direction (30degrees below the horizontal) you can tell by the length of the horizontal component (try to see the 30degree incline as horizontal, because that's the direction of the displacement). net work done on the system results in an increase in energy. i hope this can help :D, i'm also taking the ap physics 1 exam tommorow.
