From the information given, the mass of the moving body, which in this case is a person, is 72 kg and the momentum 700 kg m/s.
we use the formula p = m × v.
Where p is momentum, m is the mass and v is the velocity.
We need v so we rewrite the equation thus: v = p/m
In our case p = 700 and m = 72
v = p/m → v = 700/ 72 → v = 9.72
Therefore the person is travelling at 9.72 m/s
Answer:
Acceleration of the car will be 
Explanation:
We have given mass of the ball m = 1600 kg
Force in north direction F= 7560 N
Resistance force which opposes the movement of car 
So net force on the car 
According to second law of motion we know that F=ma
So 
Answer:
A stop watch measures time and the number of seconds making an osculation is the period T
Which is T = 2π√(L/g)........solving for L (the length of the pendulum),
Then the L = T²x g/( 4πr²) substitute and then u find length or height of the swing
Answer:
oxygen is used up is the answer
Explanation:
These vaporized molecules are drawn up into the flame, where they react with oxygen from the air to create heat, light, water vapor (H2O) and carbon dioxide (CO2).
