Answer:
6 m/s
Explanation:
mass of moving car m1=5000 kg
initial velocity of moving car vi1=?
mass of car at rest = m2=10000 kg
initial velocity of car at rest = vi2=0
final velcoities of both cars after collision = vf1=vf2= 2m/s
using conservation of momentum rule
m1vi1+m2vi2=m1vf1+m2vf2
putting values
==> 5000 × vi1 + 1000 × 0 = 5000 × 2 + 10000 × 2
==> 5000 ×vi1 = 2 × 15000
==> vi1 = 2 × 15000 ÷ 5000
==> vi1= 2×3=6 m/s
Answer:
After walking across a carpeted floor in socks, Jim brings his finger near a metal doorknob and receives a shock. What does this demonstrate? Frictional forces require direct contact. Electrical forces can act at a distance.
Answer:
FATS
Explanation:
