A body of mass 1 kg is moving with 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
Added by Jillian A.
Step 1
To do this, we subtract the initial velocity from the final velocity: Δv = v_final - v_initial = (-3i + 2j - k) - (i - 2j - 3k) Δv = -3i + 2j - k - i + 2j + 3k Δv = (-3 - 1)i + (2 + 2)j + (-1 + 3)k Δv = -4i + 4j + 2k Now, we need to find the magnitude of the Show more…

If the $\mathrm{KE}$ and momentum of a body are $100 \mathrm{~J}$ and $20 \mathrm{~kg} \mathrm{~m} \mathrm{~s}^{-1}$ respectively, the mass of the body is (a) $1 \mathrm{~kg}$ (b) $2 \mathrm{~kg}$ (c) $3 \mathrm{~kg}$ (d) $4 \mathrm{~kg}$
A force acts on a body of mass 3 kg such that its velocity changes from 4 m s -1 to 10 m s -1 . The change in momentum of the body is :
