Question

Problem

Position The figure shows a motorcyclist traveling east along a straight
road. After passing point B, the cyclist continues to travel at an average
velocity of 18 m/s east and arrives at point C2.8 s later. What is the
position of point ?

Answer 1

s = 50.4 m

Hence, the point C is 50.4 m towards east from point B

Step-by-step explanation:

Since, the motorcyclist travels at a constant speed in straight line towards east after point B. Therefore, we can use the following equation in this case:

s = vt

where,

s = distance covered = position of point C = ?

v = uniform speed of motorcyclist = 18 m/s

t = time interval = 2.8 s

Therefore,

s = (18 m/s)(2.8 s)

s = 50.4 m

Hence, the point C is 50.4 m towards east from point B
