A car is moving in a circular track of diameter 100m at a constant speed of 40m/sec. Find the centripetal acceleration.
- A
42 m/s2
- B
52 m/s2
- C
32 m/s2
- D
30 m/s2
using the formula:
ac = v2 / r
where ac is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path. the diameter of the circular track is given as 100m, which means the radius (r) is half of the diameter, so r = 50m. The constant speed of the car is given as 40 m/s.
ac = (40 m/s)2 / 50m
ac = 1600 m2/s2 / 50m
ac = 32 m/s2
Therefore, the centripetal acceleration of the car is 32 m/s2.
ac = v2 / r
where ac is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path. the diameter of the circular track is given as 100m, which means the radius (r) is half of the diameter, so r = 50m. The constant speed of the car is given as 40 m/s.
ac = (40 m/s)2 / 50m
ac = 1600 m2/s2 / 50m
ac = 32 m/s2
ac = v2 / r
where ac is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path. the diameter of the circular track is given as 100m, which means the radius (r) is half of the diameter, so r = 50m. The constant speed of the car is given as 40 m/s.
ac = (40 m/s)2 / 50m
ac = 1600 m2/s2 / 50m
ac = 32 m/s2
using the formula:
ac = v2 / r
where ac is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path. the diameter of the circular track is given as 100m, which means the radius (r) is half of the diameter, so r = 50m. The constant speed of the car is given as 40 m/s.
ac = (40 m/s)2 / 50m
ac = 1600 m2/s2 / 50m
ac = 32 m/s2
Therefore, the centripetal acceleration of the car is 32 m/s2.
