Applied Mechanics and Graphic Statics The acceleration of a train starting from rest at any instant is 1/6(V + 1) m/sec² where ‘V’ is the velocity of the train in m/sec. The train will attain a velocity of 36 km/hour after travelling a distance of 2000 m 2200 m 2300 m 2100 m 2000 m 2200 m 2300 m 2100 m ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Newton’s Law of Motion is: The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force All listed here To every action, there is always an equal and opposite reaction The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force All listed here To every action, there is always an equal and opposite reaction ANSWER DOWNLOAD EXAMIANS APP
