A stone of mass 0.05 kg is thrown vertically upwards. What is the direction and magnitude of net force on the stone during its upward motion?
0.98 N vertically downwards
0.49 N vertically upwards
9.8 N vertically downwards
0.49 N vertically downwards
F=m×g=0.05×9.8=0.49N,downwards
A stone is thrown in a vertically upward direction with a velocity of 5 m/s .If the acceleration of the stone during its motion is 10 m/s2 in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?
