a 850 g block is attached to a vertical spring whose stiffness constant is 9N/mThe block is released at the position where the spring is unextended. a) What is the maximum extension of the spring? b) How long does it take the block to reach the lowest point?
so I found w by using k=mw^2...
this is the problem:
A motorcycle and 63.6 kg rider accelerate at 3.1 m/s2 up a ramp inclined 9.1° above the horizontal. What are the magnitude of (a) the net force on the rider and (b) the force on the rider from the motorcycle?
I solved for a)
F=ma
= (63.6 kg)(3.1 m/s^2)
=...
I am having trouble with this problem I have solved most of it it is just the last part I don't understand.
Problem:
Two vectors are given by
a= ( 4.0 m)i - (3.0 m)j + (1.0 m) k
and
b= (-1.0 m)i + (1.0 m)j + (4.0 m)k
In unit-vector notation, find (a) a + b, (b)a - b, and...
kinematics question help please :)?
So I've tried to attempt this problem by finding possible things like time or velocity but it just does not come out right. Help is greatly appreciated :)

At the instant the traffic light turns green, an automobile starts with a constant...
