A particle is moving with a velocity of v =(3i^+4tj^)v=(3i^+4tj^) m/s. Find the ratio of tangential acceleration to that of normal acceleration at t = 1 sec.
Answers
Answer:
solved
Explanation:
v = dx/dt i^ + dy/dt j^ = 3i^+4tj^
dx/dt = 3
dy/dt = 4t
d²x/dt ² = 0
d²y/dt² = 4
The ratio of tangential acceleration to that of normal acceleration at t=1 s=4: 3
Explanation:
Velocity of particle , v
t=1 s
Substitute t=1
Let
Where x= Coefficient of unit vector i
y=Coefficient of unit vector j
Because
Tangential component of acceleration,
Tangential acceleration, at t=1 s
Normal component of acceleration ,
Normal component of acceleration at t=1 ,
Ratio of tangential acceleration to the normal acceleration at t=1 s
Hence, the ratio of tangential acceleration to that of normal acceleration at t=1 s=4: 3
