This question is typical on some driver’s license exams: a car moving at 49 km/h skids 13 m with locked brakes. how far will the car skid with locked brakes at 122.5 km/h? assume that energy loss is due only to sliding friction. answer in units of m.

b

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

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

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
