382.74 kJ.
Explanation:
The work that must be done to stop an 1100 kg car travelling at 59 km/h is - 382.74 kJ.
Answer:
7.5 x 10⁻⁸N
Explanation:
Given parameters:
Mass 1 = 60kg
Mass 2 = 75kg
Distance between the bodies = 2m
Unknown:
Gravitational fore = ?
Solution:
The gravitational force between the two bodies can be derived using;
F =
G is the universal gravitation constant = 6.67 x 10⁻¹¹m³kg⁻¹s⁻²
Insert the parameters and solve;
F =
= 7.5 x 10⁻⁸N
Answer:B
Explanation:
Because chemical energy fuels your body with energy so without it u wont have enough energy to move.
The kinetic energy is transferred to thermal energy through friction
Answer:
Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
