A boy throws a ball upwards with a speed of 10 m/s. The mass of the ball is 400 gram. a) Calculate its weight b) Initial Momentum of object Share with your friends Share 2 Vijay Shankar Yadav answered this Dear Student, a) Weight of the ball=mass×accelaration due to gravity=.4×10=4Nb) Initial momentum=mass of ball ×velocity of ball=.4×10=4kgm/s Regard -2 View Full Answer Bibekananda Mishra answered this mass=400 gram =400/1000 kg =2/5 kg initial speed=10 m/sec weight=mg=2/5 multiply by-9.8=2 multiply by -1.96=-3.92N so weight of object=3.92N initial momentum =mu=2/5 multiply by 10=4 kg m/s 0 Anurag Bharadwaj answered this 4n 0
