solution:
Using Cartesian co-ordinate system
Final velocity =v= -4m/s
Initial velocity = u
Acceleration a = m/s²
Time (t).= 60s
By the first kinematical equation
V= u +at
U = v – at
=(-4)-(-3)(60)
176m/s
So, initial velocity was 176m/s

Answer:

Explanation:
At the bottom the tension would be upwards and the weight downwards, their difference being the centripetal force. Taking the upwards direction as positive we then have:

where we have used the equation for centripetal acceleration. Thus we have:
