Answer:
Force exerted on the car = 4,000 N
Explanation:
Mass of the car (m) = 2000 kg
Acceleration(a) = 2 m/sec²
By Newton's second law of motion,
F (force) = m a
Putting the values of m and a
= 2000 x 2 = 4,000 N
Answer: Newton’s third law of motion

Answer:
The sample is most likely gaining thermal energy
Explanation:
The best ways to determine the safest driving speed are to 1) know the speed limit, and 2) maintain a safe following distance.<span> The safe following distance is to be enough distanced form the vehicle in front of you. But how much is enough?
A </span>driver<span> should ideally stay at least two seconds behind any vehicle that is directly in front of his or her vehicle.</span>
Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing the heat back into the air. But some of the heat istrapped<span> by the greenhouse </span>gases<span> in the </span>atmosphere<span>. ... Greenhouse </span>effect<span> of Earth's </span>atmosphere<span> keeps some of the Sun's energy from escaping back into space at night.</span>
