Two bodies having same mass 40 kg are moving in opposite directions, one with a velocity of 10 $m/s$ and the other with $7\,\mathrm{m/s}.$ If they collide and move as one body, the velocity of the combination is
Text Solution
Verified by ExpertsThe correct answer is:
D
By the conservation of momentum
$40 \times 10 + (40) \times (-7) = 80 \times v$ ⇒ ⇒ $v = 1.5 \, m/s$
