Given :
Initial velocity, u = 12.5 m/s.
Height of camera, h = 64.3 m.
Acceleration due to gravity, g = 9.8 m/s².
To Find :
How long does it take the camera to reach the ground.
Solution :
By equation of motion :
Putting all given values, we get :
t = 2.56 and t = −5.116.
Since, time cannot be negative.
t = 2.56 s.
Therefore, time taken is 2.56 s.
Hence, this is the required solution.
Answer:An inelastic collision is one in which the internal kinetic energy changes (it is not conserved). A collision in which the objects stick together is sometimes called perfectly inelastic because it reduces internal kinetic energy more than does any other type of inelastic collision.People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.
hope this helps have a nice day❤️
Explanation:
Answer : The temperature of the gas is, 43.4 K
Explanation :
The expression used for work done will be,
where,
w = work done = 200 J
n = number of moles of gas = 0.40 mol
R = gas constant = 8.314 J/mole K
T = temperature of gas = ?
= initial volume of gas = X
= final volume of gas =
Now put all the given values in the above formula, we get :
Thus, the temperature of the gas is, 43.4 K
