The answer is.......................................STEEL!!!!!!!!!!
The Kinetic Energy Formula is as follows: KE = mass x velocity^2 /2
Plug in the correct numbers into the variables!
KE = 1500 kg x 10 m/s ^2 / 2
Square the 10 m/s!
KE = 1500 kg x 100 m/s / 2
Multiply!
KE = 150,000 / 2
Divide!
KE = 75,000 Newton-meters or Joules!
Answer:
Explanation:
Given
Velocity of Huck w.r.t to raft 
Perpendicular to the motion of raft
Velocity of Raft in the river 
As Huck is traveling Perpendicular to the raft so he possess two velocities i.e. vertical velocity and horizontal velocity of River when observed from bank
So magnitude of velocity is given by
For direction 
w.r.t river bank
It is meters for most lakes hope this helps.
Answer:
the distance is 0.6 km
Explanation:
The computation of the distance is shown below:
As we know that
Distance = Speed × time
where
Speed = 72 km/h
And, the time is 30 seconds
So, the distance is
= 72 × 30
= 0.6 km
Hence, the distance is 0.6 km
