1.How much work does it take to get a 2Kg ball moving 15m/s if it starts from rest? 2. If a force of 235N was added to the ball, through what distance would this force have to act to give the ball a velocity of 15m/s

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod
