If you do this then you don't get the solution that was provided...Hamal_Arietis said:First, you must find velocity equation: v=ds/dt=f(t)
After that v=40m/s then f(t)=v=> t0
Finally, find aceleraition equation: a=dv/dt =g(t)
Replace the t0 a(t0)=g(t0)
If initial velocity is the velocity at t=0, it is not 15m/s. If you neglect the 15m/s, your answers will match the given answers.Auburn2017 said:If you do this then you don't get the solution that was provided...
Seems to me you get the given answers by taking the initial speed as 15m/s and changing the displacement to be 3t3+15t+6 to match.cnh1995 said:If initial velocity is the velocity at t=0, it is not 15m/s. If you neglect the 15m/s, your answers will match the given answers.
Right.. I meant to say neglect 14m/s and take initial velocity as 15m/s. I was about to edit but my network went off and later when I signed up again, I totally forgot that I was going to edit the post. Thanks!haruspex said:Seems to me you get the given answers by taking the initial speed as 15m/s and changing the displacement to be 3t3+15t+6 to match.
Nonuniform linear acceleration refers to a change in an object's velocity that is not constant over time. This means that the object is either speeding up or slowing down at varying rates.
Uniform linear acceleration occurs when an object's velocity changes at a constant rate, meaning it is either accelerating or decelerating at a steady pace. Nonuniform linear acceleration, on the other hand, has a changing rate of acceleration or deceleration.
Nonuniform linear acceleration can be caused by various factors such as varying forces acting on an object, changes in the object's mass or distribution of mass, and friction or air resistance.
Nonuniform linear acceleration is measured in meters per second squared (m/s^2). This unit represents the change in an object's velocity over time due to acceleration or deceleration.
Nonuniform linear acceleration is an important concept in physics as it helps us understand the motion of objects in real-world scenarios where forces are not constant. It is also essential in studying the principles of motion and how they apply to various phenomena in our universe.
