1. a car is traveling 60 miles per hours on cruise control. what is the net force?

2. an object of mass 10kg is accelerated upward at 2m/s^2. what force is required?

3. what is the mass of an object if a force of 17n causes it to accelerate at 1.5m/s/s?

    Solution: (a) The net force is zero because car is travelling with same speed that is 60 miles per hour or there is no acceleration.

    (b) Mass of object is 10 kg

    Acceleration is 2 m/s², thus force can be calculated as follows:

    F=m*a

    Here, m is mass of object and a is its acceleration thus,

    F=10 kg*2 m/s²

    =20 kg m/s²

    Here, 1 N=1 kg m/s²

    Thus, F=20 N

    (c) Force on object is 17 N and its acceleration is 1.5 m/s².

    Mass of the object can be calculated as follows:

    m=/frac{F}{a}

    thus,

    m=/frac{17 N}{1.5 m/s^{2}}=11.33 (/frac{N}{m/s^{2}})

    Here, 1 N=1 kg m/s²

    Thus,

    m=11.33 kg
