03.0 Compute the torque on an object when a 13N force acting perpendicular at a distance of 6 km. A car has a mass of 5010 kg. If the locomotive can exert a constant pull of 9000 N, compute the time it takes to increase the speed of the train from rest to 32 m/s. A car traveling at a constant speed passes a police car. Two seconds after the speeding car passes the police car, the police started to...

A locomotive of mass m= 1.134 X 105 kg uses 37.8 kW of power to accelerate at a constant rate for 15.0 s. a) The locomotive has an initial velocity of 0.500 m/s east. Calculate the locomotive’s speed after 15.0 s. After 15.0 s, the locomotive travels east at a constant speed and then collides and couples with a train of four cars. Each of the cars has half the mass of the locomotive. Before the collision, the train was...

A fugitive tries to hop on a freight train traveling at a constant speed of 5.4 m/s . Just as an empty box car passes him, the fugitive starts from rest and accelerates at a = 1.4 m/s2 to his maximum speed of 6.1 m/s , which he then maintains. How long does it take him to catch up to the empty box car? What is the distance traveled to reach the box car?
