Explanation: As the angle is increased the acceleration of the object is increased as the angle increases the component of the force parallel to the incline increases and the component of forced perpendicular to the inclined decreases it is the parallel component of the weight vector that causes the acceleration.
The answer is 175184.08 joules
Answer:
increases by a factor of 
Explanation:
First we need to find the initial velocity for it to stop at the distance 2d using the following equation of motion:
where v = 0 m/s is the final velocity of the package when it stops, 
is the initial velocity of the package when it, a is the deceleration, and 
is the distance traveled.
So the equation above can be simplified and plug in Δs = d, 
for the 1st case
(1)
For the 2nd scenario where the ramp is changed and distance becomes 2d, 
(2)
let equation (2) divided by (1) we have:
So the initial speed increases by . If the deceleration a stays the same and time is the ratio of speed over acceleration a
The time would increase by a factor of
Answer:
doubled
Explanation:
<u>Step 1</u>. Linear momentum (p) = mass X velocity = mv
p = mv -----equation 1
<u>Step 2</u>. if the mass is now twice and speed is same
p = (2*m)v -----equation 2
solving equation 1 and 2 together,
p = mv = 2mv
p = 2
Therefore, its momentum is doubled
A descriptive observation may very well be a mixture of both quantitative and qualitative as it can utilize elements of both types. Qualitative deals with the kinds of observations that cannot be measured in numerical form. Quantitative data is just that.
