Answer:
Explanation:
work done by force exerted by canon = force x displacement
= 40 x 1.7 = 68 N
This energy would have been added to the potato .
Increase in potential energy of potato = mgh
= mg sin 35 x 1.7 = 2 x 9.8 x sin 35 x 1.7 = 19.11 J
Increase in kinetic energy = 68 - 19.11
= 48.89 J
Answer:
The approximate terminal velocity of a sky diver before the parachute opens is 320 km/h.
Explanation:
- The terminal velocity is the maximum magnitude of velocity that is attained by the diver when he or she falls in the air.
- The terminal velocity of the person diving in air before opening parachute is 320 km/h that means the velocity when the person is experiencing free fall is 320 km/h.
- During terminal velocity, we can represent mathematical equation as;
Buoyancy force + drag force = Gravity
I would saw B. I choose B because translational motion is an object that shifts between one place to another.
Answer: ma is the formula of Newton's Second Law of Motion. Newton's Second Law of Motion is defined as Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration.
Explanation: Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
Answer:
Explanation:
Properties of Projectile Motion. Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola.
