Answer:
The ability of space-time to move
Explanation:
Answer:
The force exerted by the wood on the bullet is 399.01 N
Explanation:
Given;
mass of bullet, m = 0.0021 kg
initial velocity of the bullet, u = 497 m/s
final velocity of the bullet, v = 0
distance traveled by the bullet, S = 0.65 m
Determine the acceleration of the bullet which is the deceleration.
Apply kinematic equation;
V² = U² + 2aS
0 = 497² - (2 x 0.65)a
0 = 247009 - 1.3a
1.3a = 247009
a = 247009 / 1.3
a = 190006.92 m/s²
Finally, apply Newton's second law of motion to determine the force exerted by the wood on the bullet;
F = ma
F = 0.0021 x 190006.92
F = 399.01 N
Therefore, the force exerted by the wood on the bullet is 399.01 N
The strict scientific definition of work is
Work = (force) x (distance) .
If you exert a force but not through any distance, then technically,
no work has been done. You may break out in sweat, and your arm
may start to tremble and ache. But according to Physics, no work
has been done until you lift that bale a little higher.
C. Specific gravity is the answer
The answer would be that the plane would move upward and to the right! Hope this helps, message me if you need more help!
