Question

A particle move with velocity v1 for time t1 and v2 for time t2 along a straight line. The magnitude of its average acceleration is (A) (v2-v1/t1-t2) (B) (v2-v1/t1+t2) (C) (v2-v1/t2-t1) (D) (v1+v2/t1-t2)

a avg =(v2-v1/t1+t2)=( text Change in velocity / text Time interval )

Q. A particle move with velocity $v_{1}$ for time $t_{1}$ and $v_{2}$ for time $t_{2}$ along a straight line. The magnitude of its average acceleration is

$\frac{v _{2} - v _{1}}{t _{1} - t _{2}}$

$\frac{v _{2} - v _{1}}{t _{1} + t _{2}}$

$\frac{v _{2} - v _{1}}{t _{2} - t _{1}}$

$\frac{v _{1} + v _{2}}{t _{1} - t _{2}}$

$a_{a vg} = \frac{v _{2} - v _{1}}{t _{1} + t _{2}} = \frac{Change in velocity}{Time interval}$

Q. A particle move with velocity v1​ for time t1​ and v2​ for time t2​ along a straight line. The magnitude of its average acceleration is

t1​−t2​v2​−v1​​

t1​+t2​v2​−v1​​

t2​−t1​v2​−v1​​

t1​−t2​v1​+v2​​
