Answer:
69.44kJ
Explanation:
Kinetic energy is expressed as;
KE = 1/2mv^2
m is the mass = 500kg
v is the velocity
Get the velocity;
v = displacement/time
velocity = 2000/120
velcoity = 16.7m/s
Gt the kinetic energy
KE = 1/2 * 500 * 16.7²
KE = 250*277.78
KE = 69,444.4Joules
Since 1000J = 1kJ
69,444.4Joules = 69,444.4/1000
69,444.4Joules = 69.44kJ
Hence the Secretariat's average kinetic energy is 69.44kJ
Answer:
There are two different types of current in widespread use today. They are direct current, abbreviated DC, and alternating current, abbreviated AC. In a direct current, the electrons flow in one direction.
Answer:
v=10 m/s
Explanation:
Given that,
Speed of a drone is 8 m/s due East with respects to the wind
Speed of a drone 6 m/s due North with respect to the ground.
We need to find the speed of the drone with respect to the ground. Let v is the speed. It is given by the resultant of two speeds.
So, the speed of the drone with respect to the ground is 10 m/s.
