You do the net force by subtracting the sides. The direction of the box is moving forward to the right by 10 N.
Answer:
685.6 J
Explanation:
The latent heat of vaporization of ammonia is
L = 1371.2 kJ/kg
mass of ammonia, m = 0.0005 Kg
Heat = mass x latent heat of vaporization
H = 0.0005 x 1371.2
H = 0.686 kJ
H = 685.6 J
Thus, the amount of heat required to vaporize the ammonia is 685.6 J.
Answer:
how fast a car is going or an object
Hi, I crunched some numbers for you and got the following results:
Starting from initial velocity of zero (rest) the sled reached a top speed of 257.3 m/s^2.
Upon slowing down or braking, the sled slowed down very hard to about 76.35 m/s^2.
Acceleration and Gravitational Acceleration were the main interpretations obviously in this problem.
Also, if my math was correct, the speed of the sled slowing down was around 7.7 G's (acceleration due to gravity)! That is about on par with the acceleration of a F-16 Fighter Jet pulling out of a dive!--> (79 m/s^2) The human test subject probably came close to blacking out I would guess as well or very close to!
Answer:
1.53 s
Explanation:
Initially vertical component of velocity of the ball, uy = 7.5 m/s
Net displacement is vertical direction is zero, Δy =0
Use second equation of motion:
Δy = uy t + 0.5 a t²
Here, acceleration a = -g (g =9.8 m/s²)
Substitute all the values and solve for g
0 = 7.5 t -0.5 (9.8)t²
7.5 t = 4.9 t²
t = 1.53 s
