Answer:
21600
1296000
Explanation:
Full cycle consists of
1 hour = 3600 seconds
1 minute = 60 seconds
Converting to arcminutes
The arcminutes in a full cycle is 21600
Converting to arcseconds
The arseconds in full cycle is 1296000
The acceleration is 2 mph/min
Explanation:
The acceleration of an object is the rate of change of velocity. It is defined as follows:
where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to v
For the car in this problem, we have (taking North as positive direction):
u = 25 mph
v = 35 mph
t = 5 min
Substituting into the equation, we find the acceleration:
