The total force that the SUV exerts is:
F = 2000 kg * 3 m/s^2
F = 6000 N
Since a resisting force amounting to 1500 N is exerted,
then the force exerted by the SUV tires is:
F tire = 6000 N – 1500 N
F tire = 4500 N
Answer:
0.000025s
Explanation:
Period it’s. : T(s)= 1/f(Hz)=1/40000Hz=0.000025s
1. Ideal Mechanical Advantage (IMA): 9
Explanation:
For a wheel and axle system like the steering wheel, the IMA is given by:
where
is the radius of the wheel
is the radius of the axle
For the steering wheel of the problem, we see that 
and 
, so the IMA is
2. Efficiency: 88.9%
Explanation:
The efficiency of a system is defined as the ratio between the AMA (actual mechanical advantage) and the IMA:
In this problem, AMA=8 and IMA=9, so the efficiency is
Answer:

3. Attract
4 Repel
always remember when dealing with magnets, Opposites attract
