So you have to integrate?

2. A spring from the truck is found not to conform to Hooke’s law. The force law for this spring is found to be: F = – k1x – k2 x^2 where k1 = 52.8 N.m-1; k2 = 38.4 N.m-2. a) Compute the work required to stretch the spring from x = 0.500 m to x = 1.00 m. b) With one end of the spring fixed...

For b), would the force just be the F calculated in question a minus 2560 N? Cheers

Adrenaline?

Suppose there is a 2600kg stone block on a ramp inclinded at 12 degrees to the horizontal.Assume that each worker can exert a pulling force of magnitude at most 360 Newtons. a) Determine the number of workers it would take to hold the stone block at rest b)Although lubrication can reduce...

An object has an acceleration a when there are no forces acting on it. How can you use this information to find an inertial reference frame?

How do you integrate that?

a) The acceleration of a spaceship is given by a(t) = 3 m/s2 – (2 m/s3 ) t. Find the initial velocity V0 so that the spaceship is at the same point where it started after 5 seconds. No idea how to do this one, but do you need to integrate? Ty
