A car is moving in a circular parth of radius 100 m with velocity of 200 m/s such that in each sec its velocity increases by 100 m's, the net acceleration of car will be
Answers
Answer:
GIVEN THAT A CAR IS MOVING WITH SPEED 30m/s ON A CIRCULAR PATH OF RADIUS 500M . AND THE
SPEED OF CAR IS INCREASING AT RATE OF 2m/s^2 .
THERE FOR WE HAVE
SPEED OF CAR OR (VELOCITY AT FIXED MOMENT) = 30m/s
RADIUS OF TRACK = 500M
ACCELERATION = ??
NOW IN THIS CASE THERE IS TWO TYPES OF ACCELERATION THEY ARE
CENTRIPETAL ACCELERATION WHICH IS
\frac{ {v}^{2} }{radius}
radius
v
2
THAT IS EQUAL TO
\frac{ {30}^{2} }{500} = 1.8
500
30
2
=1.8
NOW SECOND ACCELERATION IS TANGENTIAL
THAT IS EQUAL TO
= 2m/s
NOW THE TOTAL ACCELERATION OR NET ACCELERATION IS
= √[ CENTRIPETAL ACCELERATION + TANGENTIAL ACCELERATION ]
WHICH IS EQUAL TO
\sqrt{ {1.8}^{2} + {2}^{2} } \: = \: 2.69 \: meter \: per \: second \: sqr

HENCE THE TOTAL ACCELERATION IS
= 2.69 m/s^2
if you didn't understand , then find the attached given there. .
v=30m/a
E=300m
a=v^2/E=900/500=1.8m/s^2
at=2m/s^2‐given
a net=root of at+a
a=root7.24
a=2.69
anet=2.7
a
net = 2.7
