Answer:
Christian
Explanation:
Given that
Force applied by Sean ,F₁=100 N
Force applied by Christian ,F₂=200 N
Lets take mass of the box = m kg
As we know that from second law of Newton's
F= m a
F=Force,m=mass ,a=acceleration
From the above we can say that acceleration a₂ is greater than a₁ is for the same mass of the box.
Therefore Christian will acceleration more for the box.
Answer:
The velocity of the truck after the collision is 20.93 m/s
Explanation:
It is given that,
Mass of car, m₁ = 1200 kg
Initial velocity of the car,
Mass of truck, m₂ = 9000 kg
Initial velocity of the truck,
After the collision, velocity of the car,
Let is the velocity of the truck immediately after the collision. The momentum of the system remains conversed.
So, the velocity of the truck after the collision is 20.93 m/s. Hence, this is the required solution.
