A bear and you are pulling in opposite directions on a picnic basket with a mass of 10 kg. The basket moves with constant velocity towards the bear, who pulls with 180 N. If the coefficient of friction is 0.5, how hard are you pulling? Draw the free body diagram and net force equations, and calculate all forces.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

technology is the application of the knowledge gained by science.
