Gary, an online physics student, has a mass of 80.5 kg. his new bicycle has a mass of 13.7 kg. gary is pedaling so that a net (unbalanced) force of 9.86 n accelerates him and his bicycle. what is the value of the acceleration?
notice the two masses are added together because the 9.86 n force accelerates the system of masses.
m = 13.7 kg + 80.5 kg = 94.2 kg
f = 9.86 n
a = ?
f = ma
a = f/m = 9.86 n/94.2 kg
f = 0.10467 m/s2
f = 0.105 m/s2

Acceleration,

Explanation:

It is given that,

Mass of Gary, m = 80.5 kg

Mass of his bicycle, m' = 13.7 kg

Net unbalanced force acting on him, F = 9.86 N

Let a is the value of acceleration. Both cycle and Gary will move with same acceleration. Using the second law of motion to find it as :

or

So, the value of acceleration of the Gary and bicycle is . Hence, this is the required solution.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
