A blue car weighing 1,302 kg is accelerating forward at a rate of 4 m/s22. What is the forward force of the car? (1 point) Responses 325.5 N 325.5 N 5,208 N 5,208 N 1,306 N 1,306 N 1,298 N
To calculate the forward force of the car, you can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
F = m * a
Given:
Mass of the car (m) = 1,302 kg
Acceleration of the car (a) = 4 m/s^2
Plugging these values into the formula, we have:
F = 1,302 kg * 4 m/s^2
F = 5,208 N
Therefore, the forward force of the car is 5,208 N.

Two bowling balls of different masses collide while accelerating at 1.875 m/s22. The first ball, rolling to the right, weighs 7 kg. The second ball, rolling to the left, weighs 4 kg. What force does the bowling ball weighing 7 kg exert on the bowling ball weighing 4 kg?(1 point) Responses 8.875 N to the right 8.875 N to the right 7.5 N to the left 7.5 N to the left 13.125 N to the right 13.125 N to the right 3.73 N to the right
To calculate the force exerted by the bowling ball weighing 7 kg on the bowling ball weighing 4 kg, you need to use Newton's third law of motion, which states that the force exerted by one object on another is equal in magnitude and opposite in direction.
Given:
Mass of the first ball (m1) = 7 kg
Mass of the second ball (m2) = 4 kg
Acceleration of both balls (a) = 1.875 m/s^2
To find the force, we need to calculate the net force on the ball weighing 4 kg. This can be done using Newton's second law of motion:
F = m * a
Plugging the values into the formula:
Force on the bowling ball weighing 4 kg (F) = 4 kg * 1.875 m/s^2
Force on the bowling ball weighing 4 kg (F) = 7.5 N
Therefore, the bowling ball weighing 7 kg exerts a force of 7.5 N to the left on the bowling ball weighing 4 kg.
To determine how an object at rest will be affected by multiple opposed but unbalanced forces, we need to understand the concept of Newton's second law of motion. This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
In the given scenario, since the forces are unbalanced, there will be a net force acting on the object. The effect of this net force will depend on the specific forces involved.
If the net force is greater than zero, it means that the combined force exerted in one direction is greater than the combined force exerted in the opposite direction. This will result in a non-zero acceleration of the object, causing it to move. Therefore, "Motion will be either created, stopped, or changed" would be the correct response.
However, it's important to note that the other options provided are incorrect. The acceleration of the object will increase only if the net force acting on it increases, not if there are opposed forces. The mass of the object will not decrease due to the presence of opposed forces. Lastly, the production of a humming sound is unrelated to the presence of unbalanced forces and depends on other factors like the object's materials and interaction with its surroundings.
