Given that:
mas (m) = 0.14 Kg ,
height (h) = 16 m,
Determine gravitational potential energy ?
Gravitational potential energy = m × g × h
= 0.14 × 9.81 × 16
= 21.97 Joules
Sam can study for hours even though it is very loud and there are many possible distractions in the common room, this is an example of a Focus system.
The focus system is a psychological intervention that is purposely designed for use at home or in lecture halls for cognitive or mental assimilation.

Answer is: 1973.17N aprox.
step by step in the pic below
To find the acceleration, we would need to use the equation acceleration= final velocity- initial velocity/elapsed time. Since the final velocity is 35 and the initial velocity is 65, we can subtract 65 from 35 first, which gives us -30. Then if we divide that by the elapsed time, which is 10, we get -3. Your acceleration is -3 meters per second.
Hope this helps! :D
Answer:
0.75 second
Explanation:
The equation is
Let t be the time when it is at 73 feet. Substitute, h = 73 in the above equation and then find the value of t.
Take positive sign
t = 0.75 second
