Sir Percival and his horse are standing still on a field of honor when Sir Rodney, atop his steed gallops by with a constant velocity of 3.00m/s. He flips Percival off as he passes by! Percival instantly begins to give chase with an acceleration of 0.600m/s2. Using Percival’s at rest position as zero, determine the time it takes for Percival to catch up to Rodney. a. 4.0 s
b. 6.0 s
c. 8.0 s
d. none of these

d. none of these

Explanation:

From the given information:

Let assume that Percival catches Sir Rodney's horse in time "t" after covering a certain distance "s"

Then, using the second equation of motion:

FOR Percival, we have:

FOR Sir Rodney;

Equating both equations together; we have:

0.3t² = 3t

0.3t² - 3t = 0

0.3t(t - 10) = 0

If Percival's position at rest = 0

Then; t = 10 s.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

50 inches should be the resultant vector
