What is the average speed of the bus that travels 450km in 5 hrs?

Suppose a truck and a car are both running at 40 km/hr.Which vehicle needs a greater force to stop and why?

Why the jeepney of mass 2000kg more difficult to stop than a tricycle of mass 1000kg?

the jeepney of mass 2000kg is more difficult to stop than the tricycle of mass 1000kg because the force applied to the former is greater than the latter. thus, a heavier object requiring greater force to move needs greater force to stop it or interfere its linear movement.

Which is harder to stop vehicle greater mass or less mass?

The greater the mass the greater the inertia. Thus if both vehicles were travelling at the same speed the vehicle with the greater mass would have the most inertia and thus be the hardest to stop.

Does rolling soccer ball needs more force to stop than a rolling bowling ball?

Any amount of force can stop either kind of ball. But a greater force is required to stop a bowling ball than to stop a soccer ball IN THE SAME TIME, because the bowling ball has more mass, and therefore more momentum and more kinetic energy.

What are Iaac Newtowns laws?

If something is stopped it needs a force to move it. If something is move it needs a force to stop it.

How does the weight of a car effect the stopping distance of a car?

The more the vehicle weighs, the harder the brakes must work to stop it and the more distance it will need to stop the vehicle. However, large trucks can brake easier with more weight because weight adds friction which helps to stop the vehicle. This still doesn't fully compensate for the total stopping distance needed for a large vehicle. Basicly what he means is the heavier the vehicle the more friction it can create(slow it down) but it can add to the forward force iswell Or more precisely, the force of the vehicle going forward because of it's mass is still greater than the force of friction helping the vehicle slow down.

What force is used to stop a vehicle?

the friction caused by the road agianst tires

A car traveling along the highway needs a certain amount of force exerted on it to stop more stopping force may be required when the car has?

If the car has a higher mass, a higher velocity, more aerodynamic shape (thereby lower drag), or it's tires have a lower friction coefficient (meaning less of the force applied makes it to the ground), it will require more force to be applied to stop the vehicle.

How does mass affect an objects inertia?

A massive object has greater inertia. It requires more force to slow it down or change it's course. Example: It takes much more force to stop a train than it does to stop a car, only because the train has much greater mass.

Why is it that the faster a car goes the greater the force needed to stop it?

Newton's first law of motion is often stated asAn object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. (Unbalanced force here being the brake force applied to the train's wheels and the friction between the wheels and the tracks/grade.)The stopping distance of that object is directly proportional to it's mass. The greater the mass, the greater the inertia. (resistance of an object to change it's present state) and momentum (weight times velocity). The faster it's going-the longer distance it needs to stop.

What Speeding is a factor in of all fatal accidents?

Speeding is a factor in all fatal accidents for multiple reasons. The main being the greater the speed, the greater force involved. More force increases the chance of great bodily harm or death in a collision. A second factor that speed changes is breaking distance. The faster a vehicle is moving, the longer it takes to stop. A vehicle traveling 30 MPH has an approximate stopping distance of 109 feet, 60 MPH 304 FT, and 90 MPH 584 FT.
