... The mosquito exerts more force on the truck than the truck exerts on the mosquito. The truck exerts more force on the mosquito than the mosquito exerts on the truck. The mosquito exerts the same force on the truck as the truck exerts on the mosquito. The truck exerts a force on the mosquito but the ...

... In part (a), 1 point was earned for a reasonable sine squared graph, but the response had maxima at one-second intervals and a difference between maximum and minimum potential energy of 0.625 J. In part (b), 2 points were earned for a cosine curve with a correct phase relationship to the given graph ...

... is about what you might expect at a major intersection in a city.) The car moves along a circular arc at a constant speed—uniform circular motion—during the turn. The direction of the net force—and thus the static friction force—must point in the direction of the acceleration. The free-body diagram ...

... Q17 A ball of mass 100 g is connected to a string that can withstand a maximum tension of 50 N before it breaks. The ball rotates in a circle of radius 20 cm on a horizontal frictionless plane. The maximum speed the ball can have before the string breaks is: (Ans: 10 m/s) Q18 A racing car, moving on ...
