Applied Mechanics and Graphic Statics A ball of mass 250 g moving on a smooth horizontal table with a velocity of 10 m/sec hits an identical stationary ball ‘B’ on the table. If the impact is perfectly plastic, the velocity of the ball ‘B’ just after impact would be 10 m/sec Zero 5 m/sec None of these 10 m/sec Zero 5 m/sec None of these ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 30 m/sec 50 m/sec 20 m/sec 40 m/sec 30 m/sec 50 m/sec 20 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A particle moves along a straight line such that distance ‘x’ traversed in ‘t’ seconds is given by x = t²(t + 1), the acceleration of the particle, will be 3t³ - 2t 6t - 2 6t + 2 3t² + 2t 3t³ - 2t 6t - 2 6t + 2 3t² + 2t ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The total kinetic energy of a hoop of mass 2 kg and radius 4 m sliding with linear velocity 8 m/sec and angular velocity 5 radian/sec is 400 J 89 J 464 J 64 J 400 J 89 J 464 J 64 J ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Two particles have been projected at angles 64° and 45° to the horizontal. If the velocity of projection of first is 10 m/sec, the velocity of projection of the other for equal horizontal ranges is 9.3 m/sec 7.3 m/sec 6.3 m/sec 8.3 m/sec 9.3 m/sec 7.3 m/sec 6.3 m/sec 8.3 m/sec ANSWER DOWNLOAD EXAMIANS APP
