Question

if the mass of a moving object is 50 kg what force is required to speed up the object at a rate of 2m/s2​

Answer 1

$\underline{ \large \green{{\huge \bf{\dag\:S \tt{olution࿐}}}}}$

• Mass of body = 50 kg
• acceleration = 2m/s²

We know that,

Force = mass × acceleration

• we need to calculate force !!

F = 50kg × 2m/s²

F = 100kg m/s²

F = 100 N

${\underline{\underline{\red{\rm{SI\:UNITS : -}}}}}$

• Acceleration = m/s²
• Force = Newton or kgm/s²
• Mass = kg

Answer 2

we know that force is equal to mass into acceleration

F = mass × acceleration

F = (50 × 2) kg m/s2

F = 100 N
