Solve the all parts of given question:
Question: The position along the axis of an object is given as a function of time by the equation x= 7+15t2+5t3 where x is in meters and t is in seconds.
Part A: What is the position at t=3 s?
Part B: What is the velocity at t=3 s?
Part C: what is the acceleration at t=3 s?
Part D: What is the acceleration constant?
Part E: What is the average acceleration for the interval t=0-3 s?
Show how you get the answer, so that I can better understand how to do it.
A uniform electric field has magnitude E = 270 N/C and is directed to the right. A particle with charge +4.3 nC moves along the straight line from a to b that is 0.25m in length, What is the work done on the particle by the electric field

A 0.12 m3 rigid tank initially contains refrigerant R-134a at 1 MPa and 100% quality. find the mass of the refrigerant that has entered the tank
A solid uniform spherical boulder rolls down the hill as shown in the figure(Figure 1) , starting from rest when it is H = 43.0{\rm m} above the bottom. The upper half of the hill is free of ice, so the boulder rolls without slipping. But the lower h..
