A train slows down as it rounds a sharp horizontal turn, going from 88.0 km/h to 56.0 km/h in
the 13.0 s that it takes to round the bend. The radius of the curve is 160 m. Compute the
acceleration (both magnitude and direction) at the moment the train speed reaches 56.0 km/h.
[Assume the train continues to slow down at this time at the same rate.]

  • A train slows down at a constant rate as it rounds a sharp circular horizontal turn....

    A train slows down at a constant rate as it rounds a sharp circular horizontal turn. Its initial speed is not known. It takes 16.4 s to slow down from 72 km/h to 27 km/h. The radius of the curve is 161 m. As the train goes around the turn, what is the magnitude of the tangential component of the acceleration? Answer in units of m/s^2. As the train goes around the turn, what is the sign of the tangential...

    Approaching one of the many sharp horizontal turns in the Monaco Grand Prix, an experienced Formula-1 driver slows down from 150 km/h to 47.0 km/h while rounding the bend in 11.0 s. If the driver continues to decelerate at this same rate and the radius of the curve is 15.0 m, what is the acceleration of the car the moment that its speed reaches 47.0 km/h? (Enter the magnitude.) m/s2

    When a high-speed passenger train traveling at vP = 158 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 692 m ahead (see the figure). The locomotive is moving at vL = 30 km/h. The engineer of the passenger train immediately applies the brakes. Assume that an x axis extends in the direction of motion. What must be the constant acceleration...

    1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...
