Jeff is driving a remote controlled car around his living room. The car has a mass of 770 g. Jeff drives the car with a velocity of 4.1 m/s. What is the momentum of the car?

3.16kgm/s

Explanation:

Given parameters:

Mass  = 770g

Velocity  = 4.1m/s

Unknown:

Momentum of the car  = ?

Solution:

To solve this problem, we use the equation below:

       Momentum  = mass x velocity

Convert the mass to kg;

        770g to kg = 0.77kg

Now;

    Momentum  = 0.77 x 4.1  = 3.16kgm/s

false br

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
