← A conducting wire bent into the shape of the parabola y² = 2x carries a current i = 2 A, from point B(2,-2) to point A(2,2) (coordinates in metres). This wire lies in a uniform magnetic field B = -4k̂ tesla (field is uniform everywhere, directed into the page). What is the magnetic force on the wire?A particle moves along the x-axis so that its position at time t is x = t³ - 6t² + 9t, where x is in metres and t is in seconds. During the first 4 seconds of the motion, from t = 0 to t = 4 s, the total distance travelled by the particle is →
