Question

A body of mass 1 kg is moving woth velocity v initial = ( i-2j-3k)m/s and after 10 sec velocity of body becomes velocity final = (-3i + 2j -k) m/s. The magnitude of change in momentum of body is A 4 kg m/s B -8√3 kg m/s C 4√3 kg m/s D 12 kg m/s

Answer 1

Answer:

Explanation:

. A particle is moved from a position r1 =3i +2j – 6k to a position r2=14i +13j + 9k under the action of force F= (4i + j + ... the force in the first 2 second? ... Another bullet, of the same mass and size and moving with a speed ... A body ascends a slope with a speed of 10 m/s.
