Answer:
kinetic Energy = 12.58 GJ
Explanation:
1 metric ton is equal to 1000 kg
then,
93000 metric ton
Mass is m = 93000 x 1000 kg
speed is v = 32 knots
1 knot is 0.514 m/s
then
,
v = 32 x 0.514 = 16.448 m/s
To solve for the Kinetic Energy (KE), we have;
KE = 0.5 x m x v²
KE = 0.5*93000*1000*(16.448)²
= 12.58 x 
J
= 12.58 GJ
Answer:
60-100
Explanation:
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.
HOPE THIS HELPS!!! HAVE A GREAT DAY!!!
<u>Statement</u><u>:</u>
A force is required to accelerate a 600 g ball from rest to 14 m/s in 0.1 s.
<u>To </u><u>find </u><u>out</u><u>:</u>
The force required to accelerate the ball.
<u>Solution</u><u>:</u>
- Mass of the ball (m) = 600 g = 0.6 Kg
- Initial velocity (u) = 0 m/s [it was at rest]
- Final velocity (v) = 14 m/s
- Time (t) = 0.1 s
- Let the acceleration be a.
- We know the equation of motion,
- v = u + at
- Therefore, putting the values in the above formula, we get
- 14 m/s = 0 m/s + a × 0.1 s
- or, 14 m/s ÷ 0.1 s = a
- or, a = 140 m/s²
- Let the force be F.
- We know, the formula : F = ma
- Putting the values in the above formula, we get
- F = 0.6 Kg × 140 m/s²
- or, F = 84 N
<u>Answer</u><u>:</u>
The force required to accelerate the ball is 84 N and this force acts along the direction of motion.
