Answer:

\omega=3.135rad/s

Explanation:

From the question we are told that:

initial Speed V_1=2.50

Mass m=70.0kg

Center of mass d=0.0.800m\

Generally the equation for angular velocity is is mathematically given by

\omega=\frac{v}{r}\\\\\omega=\frac{2.50}{0.0800}

\omega=3.135rad/s

Classify the following situations into contact and non-contact forces.
NARA [144]

Answer: Contact force

a. Applying break in a vehicle.

d. The speed of ball rolling on ground is reduced

Non contact force

b. A coconut falling from a coconut tree.

c. The planets revolving around the sun.

Explanation:

The contact force is the force which exerts when one object or entity comes in contact with other object or entity. For example, on application of break the vehicle stops, the force is applied on the breaks to stop the vehicle. The ball rolling on the ground the speed reduces so the application of force on the ground also reduces.

The non contact force is the force one object exerts on the other without coming in direct contact with the other object. The force exerted by one object on other due to gravity is a non contact force. The coconut falling on the ground and planets revolving around the sun are examples of non contact force due to gravity.

Resistance to the motion of an automobile consists of road friction, which is almost independent of speed, and air drag, which i
Troyanec [42]

Answer:

73.52983 Hp

Explanation:

m = Mass of car = \dfrac{W}{g}

W = Weight of car = 12000 N

a = Acceleration = 0.96 m/s²

Velocity of the car

v=82\times \dfrac{1000}{3600}\\\Rightarrow v=\dfrac{82}{3.6}\\\Rightarrow v=\dfrac{41}{1.8}

From the question

F=300+1.8v^2\\\Rightarrow F=300+1.8\times \left(\dfrac{41}{1.8}\right)^2\\\Rightarrow F=1233.88\ N

Balancing the forces

\dfrac{P}{v}-1233.88=ma\\\Rightarrow P=(ma+12000)v\\\Rightarrow P=\left(\dfrac{12000}{9.81}\times 0.96+1233.88\right)\dfrac{41}{1.8}\\\Rightarrow P=54853.26055\ W=\dfrac{54853.26055}{746}\\\Rightarrow P=73.52983\ Hp

The power is 73.52983 Hp
