Yes but In general I don't get it, it would be helpful if i can have some help :)Bystander said:Step 1: read the problem statement. Step 2: if it appears there's something missing, reread the problem statement.
Before the chain broke, the truck and log was maintaining a steady speed. What does that tell you about what the engine is doing?Thegiver431 said:hmmm.. ok
No. If the velocity is constant then the net force is ... ?Maged Saeed said:could we say that the net force is only the frictional force since the speed of the truck is constant ?
Oh,, the net force is zero , here .haruspex said:No. then the net force is ... ?
Right. And that zero net force is the resultant of what horizontal forces?Maged Saeed said:Oh,, the net force is zero , here .
Acceleration is the rate of change of an object's velocity over time. In simpler terms, it is how fast an object's speed is increasing or decreasing.
Acceleration is calculated by dividing the change in velocity by the change in time. The formula for acceleration is (final velocity - initial velocity) / time.
Acceleration affects the truck by changing its speed and potentially its direction. If the truck is accelerating, it will increase its speed. If the truck is decelerating, it will decrease its speed. Acceleration also affects the truck's ability to overcome resistance and maintain its momentum.
There are several factors that can impact the acceleration of a truck, including the truck's weight, engine power, road conditions, and air resistance. The heavier the truck is, the more force is needed to accelerate it. A more powerful engine can also impact acceleration, as well as the type of road surface the truck is driving on. Air resistance can also play a role in slowing down the truck's acceleration.
Acceleration is closely related to other principles of physics, such as Newton's laws of motion and force. According to Newton's second law of motion, acceleration is directly proportional to the force applied to an object and inversely proportional to its mass. This means that the greater the force applied to the truck, the greater its acceleration will be, and the heavier the truck is, the slower its acceleration will be.
