Question

Motorcycle acceleration A motorcycle is slowing down as it travels through a bend in the road. The path of the motorcycle is the gray line shown in the bird's-eye view. The black arrow represents the motorcycle's velocity at the instant shown. Three physics students make the following statements about the acceleration of the motorcycle: Alexi: "The motorcycle's acceleration is in the opposite direction to the velocity since it is slowing down." Bindi: "No, the acceleration will have two components, one opposite the velocity and the other toward the center of the curve." Carlos: "I don't think the motorcycle has an acceleration, since it is braking." With which, If any, of these three students do you agree? Alexi Bindi Carlos Explain your reasoning.

Explanation / Answer

Alexi , not agreed , there are two components od acceleration and they are acting perpendicular to each other .

Bindi , agree totally , because there is a centripetal acceleration acting towards the centre of the curve, and also a acceleration (in the opposite direction ) of velocity .

Carlos, agree, the velocity is decreasing , so it is actually deaccelerating .
