Since there is no air resistance, gravity is the only force acting on the two objects - the bowling ball and the arrow. Therefore, they will hit the ground at the same time. Thus the answer is D. Both hit the ground at the same time. Hope this helped and have a great day!
The question is incomplete. The complete question is :
A plate of uniform areal density is bounded by the four curves:
where x and y are in meters. Point has coordinates and . What is the moment of inertia of the plate about the point ?
Solution :
Given :
and , , .
So,
,
So the moment of inertia is .
Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
When the spring is extended by 44.5 cm - 34.0 cm = 10.5 cm = 0.105 m, it exerts a restoring force with magnitude R such that the net force on the mass is
∑ F = R - mg = 0
where mg = weight of the mass = (7.00 kg) g = 68.6 N.
It follows that R = 68.6 N, and by Hooke's law, the spring constant is k such that
k (0.105 m) = 68.6 N ⇒ k = (68.6 N) / (0.105 m) ≈ 653 N/m
