Answer :
Tony's speed is 40 m/s.
Work
Momentum is given by the formula:
p = mv
Where:
p = momentum
m = mass
v = velocity
We are given the mass and the momentum and need to solve for the speed (no specific direction given).
3600kg·m/s = 90 kg × v
3600kg·m/s / 90 kg = v
v = 40 m/s
Therefore, the speed of Tony would be 40 m/s.
