o m
per hour. Through what angle has it turned in 10 seconds
wirelenth 12 cmis bent en as to be along the are of a circle of radius​

Answer 1

Answer:

Solution :

• The trained turned by  0.1222 Radian (angular measurement) in 10 seconds which is equal to 7 degrees (approximately).

• Given - The radius of the circular curve = 1500 m
• Speed of the train = 66 km per hour
• Speed of the train converted to m/second = (66*1000)/3600
• ⇒ 66000/3600

• Speed of the train = 18.333 m per second

• In 1 second, distance is covered = 18.333 m

• In 10 seconds, distance is covered = 18.333*10

• = 183.333 m

• Angle turned by the train moving on the circular curve in 10 seconds
• = arc it made by moving on circular curve/radius of the circular curve
• ⇒ 183.333/1500
• = 0.1222
