Answer:
the awnser is momentum i did this before
Explanation:
shown below
2 x 10⁷ as a number is 20,000,000
20,000,000 - 10 = 19,999,990
It went 19,999,990 m/h
in km/h:
19,999,990 / 1000 = 19,999.99 km/h
in km/s
19,999,990 / 3,600,000 = ~5.56 km/s
in m/s
19,999,990 / 3600 = ~5555.56 m/s
4440N
Given parameters:
Mass = 444kg
Acceleration due to gravity = 10m/s²
Unknown:
Tension in the cable = ?
Solution:
The tension in the cable is due to the weight of the mass it is suspending.
So;
Weight = mass x acceleration due to gravity
Weight = 444 x 10 = 4440N
