Answer:
by using it in a such place or thing which needs it or which can work with it
Answer:
3,200 grams
Explanation:
recall that a hectogram = 100 grams
therefore
32 hectograms = 32 x 100 = 3,200 grams
Answer:
The work done by friction was
Explanation:
Given that,
Mass of car = 1000 kg
Initial speed of car =108 km/h =30 m/s
When the car is stop by brakes.
Then, final speed of car will be zero.
We need to calculate the work done by friction
Using formula of work done
Put the value of m and v
Hence, The work done by friction was
Kinetic energy = 1/2 x mass x velocity²
10.0km x 100 = 10000m
Kinetic energy = 1/2 x 100 x 10000²
Kinetic energy = 5000000000J
