Answer:
Speed of the car after the collision is 1.2 m/s
Explanation:
It is given that,
Mass of first car, m₁ = 2 kg
Velocity of first car, v₁ = 6 m/s
Mass of second car, m₂ = 3 kg
Velocity of second car, v₂ = -2 m/s (it is travelling in opposite direction)
The two cars lock together and move along the road. This shows an inelastic collision. Let their common velocity is V. On applying the conservation of momentum as :
V = 1.2 m/s
So, after collision the speed of the cars is 1.2 m/s. Hence, this is the required solution.
Answer: 2 days = 172,800 seconds
Explanation: 1 day is equal to 86,400 seconds so 2 days equal to 86,400 x 2 = 172,800 seconds.
Humans rely on photosynthesis to generate food as well as provide energy for heating, lighting, and electricity.
Probably not strong because the car weights 2000 more than the rope
