Answer:
the final velocity of the wagon is 6 m/s.
Explanation:
Given;
initial velocity of the wagon, u = 4 m/s
mass of the wagon, m = 35 kg
energy applied to the wagon, E = 350 J
The final velocity of the wagon is calculated as;
E = ¹/₂m(v² - u²)
Therefore, the final velocity of the wagon is 6 m/s.
Answer:
(a). The net gravitational force is
(b). The position is at 0.232 m.
Explanation:
Given that,
Mass of one object M = 255 kg
Mass of another object M'= 555 kg
Separation = 0.390 m
(a). We need to calculate the net gravitational force
Using formula of force
Put the value into the formula
The net gravitational force is
(b). We need to calculate the position
Force from 555 mass = Force from 255 mass
The position is at 0.232 m.
Hence, (a). The net gravitational force is
(b). The position is at 0.232 m.
