I don't have the question and answe on me but I will post it tomorrow Thanks for replying, I've no idea how to do this and it's bugging me

Homework Statement See attached picture Homework Equations For any rectangular prism, the formulas are the following: Surface Area = 2(lw + wh + hl); l is length, w is width, and h is height. Volume = lwh; l is length, w is width, and h is height. For a square-based prism, the formulas are...

v will = 0 at rest, but if the initial velocity is also 0 and final velocity is 0 also then I don't know how I can get the desired answer if that made sense

Displacement is the antiderivative of velocity so I can find the intergral of the given equation, I'm still not sure about the first question on finding the time it stopped

Sorry about the multiple post, thanks for the help but

Homework Statement The velocity of a tram traveling on a straight line between two stops is given by: v = 16sin(pi(t)/30) m/s find the time lapse between stops the distance traveled between stops the maximum velocity of the tram and when it occurs Homework Equations Displacement = x...

Homework Statement A missle is fired vertically up from a ground with an initial velocity of 20m/s. The acceleration at any time is given by dv/dt = -10 + t/2 m/s^2. Find the height of the missile after two seconds Find the height after four seconds the direction the missile is traveling when t...

The rod is stable when the Y-Axis (Deflection) is equal to zero and so I lengthened the time (X-axis) it took for it to have the deflection = 0 Does that make sense?

I substituted t into d(t) = -5e^(-5t) cos (10t) and then on the graph I changed the value d(t) = -5e^(-2t) cos (10t) which in turn when graphed changed the time when the damper had converged to about 0 at pi/3 and lengthened the time

Homework Statement [/b] Develop a mathematical model that would lengthen the time until the shock stabilised by the given time. T= 2.51 show mathematical analysis of the situation d(t) = -5e^(-5t) cos (10t) is the original equation for a deflection of a rod in centimetres where t is time...

Solved it thank you, I found the constant and worked from their, thank you

I can't seem to figure it out, I'm not very good with intergration by parts :(

The current of a regenerative shock absorber is modeled by I = -5e^(-0.5t) cos t - 10e^(-0.5t) sin t Given that the charge, q, in an electrical current is related to, I by I = dq/dt and that at t = 0 the charge of the regenerative shock absorber is q=80, find the charge when t = 5 Hint=...
