Answer:
a₂ = 1.9 m/s²
Explanation:
Newton's third law or principle of action and reaction :
Force of the boy on the girl = - Force of the girl on the boy
Fbg = - Fgb Formula (1)
Newton's second law
∑F = m*a Formula (2)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
a : acceleration in meters over second square (m/s²)
Newton's second law to the girl
m₁ : girl mass
a₁ : acceleration of the girl toward the boy
∑F = m₁*a₁
Fbg= (40kg)*(3 m/s²)
Fbg = 120 N
Newton's second law to the boy
m₂: boy mass
a₂ : acceleration of the boy toward the girl
∑F = m₂*a₂
Fgb = (63)*a₂
120 = (63)*a₂
a₂ = 120 / (63)
a₂ = 1.9 m/s²
Answer:
TECHNICIAN B
Explanation: Drive shaft is an elongated part of the drive system made of steel of a vehicle that transmits the <em>ENGINE TORQUE to the WHEELS</em> of a vehicle. For proper inspection a technician is expected to completely remove the driveshaft to check all its compactment. It is Cylindrical and usually used for <em>REAR-WHEEL-VEHICLES</em>. Drive shafts are known by different names like propeller shaft,Cardan shaft etc it has different types which range from
<em>One-piece drive shaft
,Two-piece drive shaft to Slip-in-tube drive shaft
.</em>
