Answer:
3.9m/s
Explanation:
divide 95 with 24 to get your acceleration
Answer:
a) F = μk mg Cosθ
b) F = 279.78 N
Explanation:
a) F = μk R
Based on the description in the question, the horizontal reaction is:
R = mg Cosθ
The force required to move the box with constant speed in terms of m, μk, θ, and g is :
F = μk mg Cosθ
b) If m = 90 kg
g = 9.8 m/s²
μk=0.35
θ = 25⁰
Force required to slide the 90-kg patient across a floor at constant speed by pulling on him at an angle of 25∘ above the horizontal will be:
F = μk mg Cosθ
F = 0.35 * 90 * 9.8 * cos25
F = 279.78 N
Answer:
Aristotle
Explanation:
In ancient Greece, the popular
philosopher Aristotle declared
that all matter was made of only
