Question

3 women push a stalled car. Each woman pushes with a 423 N force. What is the mass of the car if the car accelerates at 0.82 m/s²?

Answer 1

Heya!!!

Amount of force applied by each woman=423N

therefore,

the net force applied

= (3×423)N

acceleration of the car=0.82m^2

FORCE= MASS × ACCELERATION

$\implies \: 3 \times 423 = 0.82 \times m \\ \implies \: m = 3 \times 423 \div 0.82 \\ \implies \: m = 1547.56kg$

here m is the mass of the car

thus, the mass of the car is 1547.56kg

Answer 2

Answer:

mass of the stalled car is 1547.56 kg

force applied by each woman=423 N

net force=force applied by 3 women

net force=423×3 N=1269 N

in case of car

acceleration of car=0.82 m/s² (given)

force applied on car=1269 N (calculated above).

force= mass × acceleration

mass = force/ acceleration

mass =1269/0.82

mass= 1547.56 kg (approx)

mass of the stalled car is 1547.56 kg
