An inclined plane is 100m long and at an angle of 20°to the horizontal the AMA of the slope is two. calculate a.)the effort required to push a7200N block up the slope
b) the ideal mechanical advantage

c) the efficiency of the slope

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

we need to know the time interval during which the force acts. impulse of force = momentum change

cancer risk hope this
