Question

Pls answer this question it is the last question of my project and I have to sumbit it today by 8:30 am pls help me pls I will be very thankful if you will help me

Answer 1

Answer:

If the radius of clock is "r" meters

1) From 2:00 to 2:30

Distance covered is half the perimeter

∴ Distance covered in 2:00 to 2:30 is πr meters.

Displacement covered is diameter

∴ Displacement covered in 2:00 to 2:30 is 2r meters.

Speed = distance / time = πr/30 mins = (πr / 1800) m/s

Velocity = displacement / time = 2r/30 mins = (r / 900) m/s

2) From 2:00 to 3:00

Distance covered is the perimeter

∴ Distance covered in 2:00 to 3:00 is 2πr meters.

Displacement covered is zero

∴ Displacement covered in 2:00 to 2:30 is 0 meters.

Speed = distance / time = 2πr/60 mins = (πr / 1800) m/s

Velocity = displacement / time = 0/30 mins = 0 m/s
