Answer: hello your question lacks some data attached below is the missing data
answer : T - mg = ma
Explanation:
Given that the vine has a fixed end and Tarzan's path is circular
At Tarzans lowest point the point can be expressed as shown below.
It can be expressed as : T - mg = ma
The final speed of the cart and the bag is 2.2 m/s
Explanation:
We can solve this problem by using the law of conservation of momentum: in fact, in absence of external forces, the total momentum of the bag and the cart must be conserved before and after the collision.
Mathematically:
where:
is the mass of the bag of rice
is the initial velocity of the bag
is the mass of the cart
is the initial velocity of the cart (at rest)
is the final combined velocity of the bag and the cart
Re-arranging the equation and solving for v, we find:
