Explanation:
Momentum = mass x acceleration
5 x 2 = 10 kg. m/s
Answer:
The true weight of the aluminium is
4.5021 kg
Explanation:
Given data
= 4.5 kg
= 1.29 
= 2.7× 
The true mass of the aluminium is given by

Put all the values in above equation we get

4.5021 kg
Therefore the true weight of the aluminium is
4.5021 kg
1350kgm/s
Explanation:
Given parameters:
Mass of Sam = 75kg
Velocity = 18m/s
Unknown:
Momentum = ?
Solution:
Momentum is the property of a moving body with respect to its mass and velocity.
Objects in motion have momentum. The more the velocity of a body, the more its momentum. Also, the more the mass of an object, the more momentum it possess.
Momentum is a function of the mass and the velocity of a body
Momentum = mass x velocity
Momentum = 75 x 18 = 1350kgm/s
