Answer:
Explanation:
From the question we are told that:
coefficient of static friction
Velocity
Generally the equation for Conservation of energy is mathematically given by
Answer:
1863 J
Explanation:
F = Force moving the object
f = Frictional force = 230 N
The forces in the horizontal direction have the force balance
So, the force by which the object is being pushed is
s = The displacement of the object = 8.1 m
Work done is given by
The work done by the mover is 1863 J.
Answer:
Explanation:
5 C = 278 K
25 C = 298 K
V1 / T1 = V2 / T2
1.5L / 278 K = V2 / 298 K
V2 = (1.5L * 298) / 278
V2 = 1.61 L
