Answer:
law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.
can u give me
your crown to me please brainliest me id you like my answer
X=.5(a)t^2 can be used: 2.5m=.5(g)(1), g=5m/s^2.
The magnitude of the force<span> a 1.5 x 10-3 C charge exerts on a 3.2 x 10-4 C charge located 1.5 m away is 1920 Newtons. The formula used to solve this problem is:
F = kq1q2/r^2
where:
F = Electric force, Newtons
k = Coulomb's constant, 9x10^9 Nm^2/C^2
q1 = point charge 1, C
q2 = point charge 2, C
r = distance between charges, meters
Using direct substitution, the force F is determined to be 1920 Newtons.</span>
Answer:
T = 2.82π s
x = Acos(0.71t)
Explanation:
This problem can be solved by using the expressions
( 1 )
( 2 )
where T is the period of oscillation of the system, m is the mass of the object attached to the spring, k is the spring constant and x is the position of the object.
By replacing in the expression (1):
Taking 6 inches as the amplitude of the motion, we have
I hope this is useful for you
