Question

The displacement of a particle having position vector 2i +2j , 2i-2j and -4i are acting together on a point object at rest. The object moves along which direction

Answer 1

Answer:

Net acceleration is the resultant acceleration of centripetal acceleration and tangential acceleration thus find both of them as follows:

A

c

− be centripetal acceleration.

A

t

− be tangential acceleration

A

net

=

(A

c

)

Now then,

A

c

is

A

t

is given as 2.m/s

, thus

A
