If two objects are under the influence of equal forces, they have the same acceleration.
1. True False During the collision of a locomotive with a car, the car exerts an equal size force on the locomotive as the locomotive exerts on the car.
2. True False The net force which acts on an object which maintains a constant velocity is zero.
3. True False An object's velocity will change if a net force acts on the object.
4. True False If a net force acts on an object, the object's speed will change.
5. True False A bicycle initially moving at a constant velocity will slow down unless a small net force is applied.

Explanation:

If two objects are under the influence of equal forces, they have the same acceleration  - False .

If their mass differs , their acceleration will also change.

1 )During the collision of a locomotive with a car, the car exerts an equal size force on the locomotive as the locomotive exerts on the car

True because action and reaction forces are equal.

2. True False The net force which acts on an object which maintains a constant velocity is zero

True , because if acceleration is zero , net force will be zero.

3. True False An object's velocity will change if a net force acts on the object.

True , because , if there is acceleration , there is force.

True False A bicycle initially moving at a constant velocity will slow down unless a small net force is applied

False , A bicycle initially moving at a constant velocity will  not slow down

unless a small net force is applied .

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
