Question

Five persons A , B , C , D and E are pulling a cart of mass 100 kg on a smooth surface and the cart is moving with an acceleration of 3 m s- 2 in the east direction. If another person F comes and starts pulling the cart with a force of 100 N due west, then the acceleration of the cart will be (A) 2.5ms- 2 (B) 1ms- 2 (C) 2ms- 2 (D) 4ms- 2

Due to the five people the net force on the cart is F1=100× 3=300N due east After the force applied by the person F , the net force is Fnet=300-100=200N Fnet=200=100× a ⇒ a=2ms- 2

$2.5 m s^{- 2}$

$1 m s^{- 2}$

$2 m s^{- 2}$

$4 m s^{- 2}$

Due to the five people the net force on the cart is
$F_{1} = 100 \times 3 = 300 N$ due east
After the force applied by the person $F$ , the net force is
$F_{n e t} = 300 - 100 = 200 N$
$F_{n e t} = 200 = 100 \times a$
$\Rightarrow a = 2 m s^{- 2}$

Q. Five persons A , B , C , D and E are pulling a cart of mass 100kg on a smooth surface and the cart is moving with an acceleration of 3ms−2 in the east direction. If another person F comes and starts pulling the cart with a force of 100N due west, then the acceleration of the cart will be

2.5ms−2

1ms−2

2ms−2

4ms−2

Due to the five people the net force on the cart is F1​=100×3=300N due east After the force applied by the person F , the net force is Fnet​=300−100=200N Fnet​=200=100×a ⇒a=2ms−2

$2.5 m s^{- 2}$

$1 m s^{- 2}$

$2 m s^{- 2}$

$4 m s^{- 2}$

Due to the five people the net force on the cart is
$F_{1} = 100 \times 3 = 300 N$ due east
After the force applied by the person $F$ , the net force is
$F_{n e t} = 300 - 100 = 200 N$
$F_{n e t} = 200 = 100 \times a$
$\Rightarrow a = 2 m s^{- 2}$
