Question A1 The acceleration of a particle in clockwise circular
motion is 𝑎⃑1 = 7𝑖̂+ 3𝑗̂m/s 2 at 𝑡1 = 2 s. It moves at constant
speed 𝑣. The particle’s acceleration is 𝑎⃑2 = 7𝑖̂− 3𝑗̂m/s 2 at time
𝑡2 = 4. 8s. Given that 𝑡2 − 𝑡1 is less than one period. (a)
Determine the angle between 𝑎⃑1 and 𝑎⃑2. (6 marks) (b) Determine
the speed 𝑣 and the radius 𝑟 of the path taken by the particle.
