This item is solved through the concept of the conservation of momentum which states that the momentum before and after collision should be equal.
momentum = mass x velocity
(1,600 kg)(16 m/s) + (1.0x10^3 kg)(10 m/s) = (1600 + 1000 kg)(x)
The value of x is 13.69 m/s. Thus, their final speed is approximately letter D. 14 m/s.
Answer:
hope this helps
Explanation:
Coating surfaces with oil reduce friction between the surfaces because it is like when lubricating a machine, it makes it run or it makes it become smoother.
Answer: acceleration is 6 m/s²
Explanation: V = vo + at. If initial speed Is zero,
V = at and a= V/t = 3m/s /0.5 s
Since the orange rolls off the table and is (falling) its potential energy turnes into kinetic energy.

Explanation:
Tornado chasers are meteorologist who study and predict weather pattern. This helps them in forecasting time and location of the storm. Never the less tornado's and hurricane's can be deadly as they are powerful wind and comes with a little warning. Storm chaser are in path of storm placing scientific equipment's and hoping to get some reading and then quickly they have to retreat themselves to safe place as even a small delay could cost them their lives. Thus,we can say that life of a tornado chaser would be exciting and dangerous.
