It takes around 4 seconds for the camera ro fall 250 feet
use the quadratic formula where a=-16 b=0 and c=250
Explanation:
The inductive reactance 
is given by
Solving for f, we get
Answer: Both forces are equal each other.
Explanation:
If we assume that no external forces act during the collision (based on the fact that the collision time is very small), total momentum must be conserved, and Newton's 3rd law must apply.
If the total momentum is conserved, the change in momentum for the automobile (caused by the truck) must be equal to the one caused to the truck by the car.
This change in momentum is caused by internal forces, which must be equal each other (even though of opposite signs).
Another way to explain this, is that by Newton's 3rd Law, the force applied by the automobile to the car, must be equal and opposite to the one the truck is applying to the car at the same time.
Answer:
The value is 
Explanation:
From the question we are told that
The mass of the Ping-Pong is 
The terminal speed is 
The drag force is 
Generally the resultant force on the Ping- Pong is mathematically represented as
when terminal velocity is attained , the resultant force is zero so
=> 
=> 
=>
The acceleration will be slower
Law of inertia
F=Ma 2 times slower
