Ria and Rony are walking along a circular track of boundary 31400m in anticlockwise direction. Ria completes half the track and stops whereas Rony completes the entire path. Ria takes 30 minutes and Rony takes 1 hr. Find their speed and velocity. (consider pi= 3.14). What conclusion did you deduce from their speeds?

Answer:
Answer:Radius = 10÷2 = 5m
Answer:Radius = 10÷2 = 5mFor distance:
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circle
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circleThat is 2piR = 10pi
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circleThat is 2piR = 10piNow distance in 4.5 rounds = 10pi×4.5 = 45pi = 141.37m
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circleThat is 2piR = 10piNow distance in 4.5 rounds = 10pi×4.5 = 45pi = 141.37mNow for displacement:
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circleThat is 2piR = 10piNow distance in 4.5 rounds = 10pi×4.5 = 45pi = 141.37mNow for displacement:We know that displacement is the shortest parh from initial point to final point.
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circleThat is 2piR = 10piNow distance in 4.5 rounds = 10pi×4.5 = 45pi = 141.37mNow for displacement:We know that displacement is the shortest parh from initial point to final point.Here, after taking four complete rounds displacement will be 0 ( object will be at the same position that is initial )
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circleThat is 2piR = 10piNow distance in 4.5 rounds = 10pi×4.5 = 45pi = 141.37mNow for displacement:We know that displacement is the shortest parh from initial point to final point.Here, after taking four complete rounds displacement will be 0 ( object will be at the same position that is initial )And when another half round will complete the object will be on opposite side of initial point.
Answer:Radius = 10÷2 = 5mFor distance:Distance in one round = circumference of circleThat is 2piR = 10piNow distance in 4.5 rounds = 10pi×4.5 = 45pi = 141.37mNow for displacement:We know that displacement is the shortest parh from initial point to final point.Here, after taking four complete rounds displacement will be 0 ( object will be at the same position that is initial )And when another half round will complete the object will be on opposite side of initial point.Then displacement is equal to diameter of circle. That is 10m
