A point moves on the xy plane according to the law x = a sin ω ω t and y = a (1 – cos ω ω t) where a and ω ω are positive constants. Find the distance covered in time t 0 .
A
a ω ω t 0
B
C
2a (sin ω ω t 0 /2)
D
2a (cos ω ω t 0 /2)
Text Solution
Verified by ExpertsThe correct answer is:
A
v x = a ω ω cos ω ω t and
v y = a ω ω sint ω ω t
or v = a ω ω cos cot 
+ a ω ω sin ω ω t 
or |v| = a ω ω
s = |v|t 0 = a ω ω t 0 .
