The mass is 28000kg,so 28000x2=56000 Ngneill said:You'll need to provide the mass of the lorry. That will be the "m" in your f = ma.
Presumably the motion that is of interest here is in the horizontal direction, and the lorry is accelerating along a level road surface. Gravity operates in the vertical direction, and the road surface prevents motion in that direction. The vertical force due to gravity (weight) does not contribute to motion in the horizontal direction.fleur said:The mass is 28000kg,so 28000x2=56000 N
would i just multiply it by the acceleration of 2 ms-2 but what about the acceleration due to gravity
Thrust is the force that propels an object forward. It is important in science because it helps us understand how objects move and interact with their environment. For example, calculating thrust is crucial in designing rockets and understanding how they can travel through space.
Thrust is calculated by multiplying the mass of an object by its acceleration. This is known as Newton's Second Law of Motion, which states that force is equal to mass times acceleration (F=ma). In simpler terms, the greater the mass of an object and the faster it accelerates, the greater the thrust will be.
Calculating thrust has many practical applications, including designing aircrafts, rockets, and other vehicles that require propulsion. It is also used in understanding the motion of objects in space, such as satellites and planets. Additionally, thrust is important in studying fluid dynamics and understanding how objects move through air and water.
Yes, there are several formulas and equations used to calculate thrust depending on the specific scenario. Some common ones include the thrust equation (T=mdot * Ve), where mdot is the mass flow rate and Ve is the exhaust velocity, and the thrust coefficient (Ct=T/(p * Ae * Ve^2)), where p is the density of the fluid and Ae is the exit area of the nozzle.
Thrust is directly related to an object's acceleration, which in turn affects its overall motion. The greater the thrust, the faster an object will accelerate and the quicker it will move. On the other hand, if thrust is less than the opposing force (such as gravity or air resistance), the object will slow down or change direction. This is why understanding and calculating thrust is crucial in accurately predicting an object's motion.
