⟹\bold{40 - 16(3m - 5) = - 10(4m - 8)}

⟹\bold{40 - 48m + 80 = - 40m + 80}

⟹\bold{40 + 80 - 48m = - 40m + 80}

⟹\bold{120 - 48m = - 40m + 80}

⟹\bold{120 - 80 = - 40m + 48m}

⟹\bold{40 = 8m}

⟹\bold{\red{m = \frac{40}{8} = 5}}

\mathcal{CHECK:-}

⟹\bold{40 - 16(3(5) - 5) = - 10(4(5) - 8)}

⟹\bold{40 - 16(15 - 5) = - 10(20 - 8)}

⟹\bold{40 - 16(10) = - 10(12)}

⟹\bold{40 - 160 = - 120}

⟹ \bold{- 120 = - 120}

Therefore,L.H.S=R.H.S

Answer:

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

2

+A

t

2

)

Now then,

A

c

is

R

V

2

=

10

25

=2.5m/s

2

A

t

is given as 2.m/s

2

, thus

A

net

=

(2.5

2

+2

2

)

=3.20m/s

2

.

Hence,

option (A) is correct answer.
