CAPE Physics Unit 1 · 2003 · Paper 2 · Question 4(c)(i)

Figure 2 shows a small 50 g mass moving on the end of a string in a horizontal circle of radius 0.20 m. The string is at an angle of 38.3° with its support. The time for one revolution is 0.8 s.

Calculate the angular velocity, ω, and centripetal acceleration of the mass.

This question uses a figure or table from the paper — you'll see it when you practise.
