From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s

Explanation:
The period T of oscillation of the pendulum is given by the formula:
The maximum oscillation point it can reach is 45 °,
This point is the equivalent of T / 4, which is the moment when it reaches equilibrium.
So for T / 4,
