The graph above shows the velocity v as a function of time t of a 0.50 kg mass. There are three segments during which a constant force is applied. What is the change in kinetic energy of the system during segment 2?

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
