Answer:
Speed. I am speed.
Explanation:
The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. A single lap should be completed each time you hear this sound. Remember to run in a straight line, and run as long as possible.
More force and 50 grams of water
Answer:
1362000 kgm/s
Explanation:
So the total mass combination of the plane and the people inside it is
M = 35000 + 160*65 = 45400 kg
After 15 seconds at an acceleration of 2 m/s2, the plane speed would be
V = 2*15 = 30 m/s
So the magnitude of the plane 15s after brakes are released is
MV = 45400 * 30 = 1362000 kgm/s
Answer:
K.E = 1490.73 J
Explanation:
Given:
Speed of the ball (V)= 139 km/h = 38.61 m/s
Moment of inertia, I = 0.720 kg-m²
Distance, r = 0.600 m
Angular velocity (ω) =
(ω) = =64.35 rad/sec
The kinetic energy (K.E) is given as
K.E =
substituting the values in the above equation we get
K.E =
K.E = 1490.73 J
