Answer:
u = 1.77 m/s
Explanation:
Conservation of momentum
2250(10.3) + 3160u = (2250 + 3160)(5.32)
u = 1.77 m/s
you would multiply 30 by 15. because its the weight times the distance.
<span>The image produced is real and enlarged.
Check for various positions of objects and Images for convex lens.
Note at position of 2F, the image is same as the object, and once it is between 2F and F, the image becomes bigger than the object. </span>
Explanation:
It is given that,
Mass of the artillery shell, m = 1100 kg
Acceleration of he shell,
(a) The magnitude of force exerted on the shell can be calculated using Newton's second law of motion as :
F = ma
F = 26400000 N
or
(b) The magnitude of the force exerted on the ship by the artillery shell will be same but the direction is opposite as per Newton's third law of motion. i.e
