Calculate the linear acceleration of a car, the 0.220-m radius tires of which have an angular acceleration of 13.0 rad/s2. Assume no slippage and give your answer in m/s2. m/s2 (b) How many revolutions do the tires make in 2.50 s if they start from rest

a). 2.86

b). 6.465 revolutions

Explanation:

Given :

a). Radius of the tires, r = 0.220 m

    Angular acceleration of the tires, α = 13.0  

The line acceleration is defined as the rate of change of velocity with changing in direction.

The linear acceleration is equal to the product of the angular acceleration and the radius.

Therefore, linear acceleration is given by :

a = α x r

  = 13 x 0.22

  = 2.86

b). Given time , t = 2.5 s

   The angle moved is given by :

      = 40.625 rad

Number of revolutions is

n = 6.465 revolutions  

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
