Since I have a textbook without that ans for a certain section, that's why I want to check did I do these questions in the right way. Please tell me the right answers and show me the steps if I got them wrong. Thank you
This is the question:
The instrument attached to a weather balloon have a mass of 5.0kg.
a. The balloon is released and exerts an upward force of 98N on the instruments,What is the acceleration of the balloon and instruments?
I got 20m/s^2
b. After the balloon has accelerated for 10 s, the instruments are released. What is the velocity of the instrument at the moment of their release?
I got 196 m/s
c. What net force acts on the instruments after their release?
I got 147N
d. When does the direction of their velocity first become downward?
When the instrument stopped going upward and start falling.
Once again, thank you so much for helping me :!)
