Answer:
When the denominator of both ratios is the same, adding the ratio is simple. You just add the numbers to the left of the colon (this number is called the Ratio Numerator)xplanation:
Answer:
Explanation:
Given that,
An object starts from rest at the origin (x₀ = 0) and travels in a straight line with a constant acceleration (a = constant).
The relation between the position (x) and time (t) is given by :
Let v is the velocity of the object.
Let a is the acceleration of the object. It is given by :
So, the acceleration of the object is . Hence, this is the required solution.
It goes faster or slower because there is more space inbetween
a) Change in Kinetic energy = Work Done
We require Normal Force N,
N + 188 X sin(28.6 ) - m x g = 0
so N = m x g - 188 x sin(28.6)
= 19.7 Kg x 9.8m/s^2 - 188 x sin(28.6)
= 19.7 Kg x 9.8m/s^2 - 188 x 0.478
= 193.06 Kg.m/s^2 - 89.864 N
= 103.196 N
Wvertical = F*x = μ X 103.196 x 48.7 = 0.103 X 103.196 x 48.7
= 517.641 N
Whorizontal = F*x = F x cos(28.6 ) x 48.7
= 188 x cos(28.6 ) x 48.7
= 188 x 0.877 x 48.7
= 8029.46 J
b) V^2 = U^2 + 2 x a x s
V = (2 x a x s)^0.5
= 13.486 m/s
