A 1100-kg car pulls a boat on a trailer. (Enter the magnitude.) (a) What total force (in N) resists the motion of the car, boat,

and trailer, if the car exerts a 1860-N force on the road and produces an acceleration of 0.600 m/s2

Answer:

780 N  

Explanation:

The combined mass of boat and trailer is, m= 700 kg.

Force applied by car, F= 1860 N

acceleration produced on the total system, a = 0.600 m/s²

Apply Newton's second law:

F-F_r=m_na

m_n=700+1100 =1800 kg

Substitute the values:

1860-F_r=1800\times0.6\\F_r=780 N

What is the magnitude of the angular momentum (in kgm2/s) of a 40 g golf ball flying through the air and spinning at 4300 rpm af
sladkih [1.3K]

Answer:

L=0.0045\ kg-m^2/s

Explanation:

Given that,

The mass of a golf ball, m = 40 g = 0.04 kg

Its angular velocity, \omega=4300\ rpm=450.29\ rad/s

The radius of the sphere is 2.5 cm or 0.025 m

We need to find the magnitude of the angular momentum of the ball. It is given by the formula as follows:

L=I\omega

Where I is moment of inertia

For sphere, I=\dfrac{2}{5}mr^2

L=\dfrac{2}{5}mr^2\omega\\\\L=\dfrac{2}{5}\times 0.04\times (0.025)^2\times 450.29\\\\L=0.0045\ kg-m^2/s

So, the magnitude of the angular momentum of the sphere is 0.0045\ kg-m^2/s.
