Answer: F=32.2m</h2>
Explanation:
According Newton's 2nd Law of Motion the force is directly proportional to the mass and to the acceleration of a body:
(1)
When we talk about the force of gravity on an object (the weight) the constant acceleration is due gravity, this means:
(2)
Substituting (2) in (1):
(3)
This means the equation that best represents the force on an object due to gravity according to its mass, among the given options is:
To find the acceleration of the car, we can use the equation acelleration=final velocity-initial velocity/elapsed time. Since we know the initial velocity is zero from the start, than we can calculate it as final velocity/elapsed time. If we divide 36 by 10, we get 3.6. Your acceleration is 3.6 km/h.
Hope this helps! :D
Internal energy of the system changes by ΔE = 178 J.
Heat given to the system = Q = +658 J.
According to the first law of thermodynamics,
ΔE = Q + W
178 = 658 + W
∴ W = 178-658 = -480 J
Minus sign indicates that work is done by the system.
