Answer:
B. 80 m/s²
Explanation:
F = ma
a = F/m = (40 N)/(0.5 kg) = 80 m/s²
78.4 F because you do 8.00 muliplyed by 9.8
Answer:
A 300-kg crate is placed on a adjustable incline plane. as one end of the incline is raised, the crate begins to move downward. if the crate slides down the plane with the acceleration of .70 m/s2 , when the incline is 25 degrees, what is the coefficient of kinetic friction between ramp and crate?
Explanation:
Answer:
30%
Explanation:
Total profit=$25000
Initial investment=$10000
Return on investment is given by
RoI=(Gain from investment-cost of investment)/cost of investment

RoI=150% but since it's over 5 years, we distribute for 5 years hence annual 
Therefore, RoI=30%
