From the information given, there is 1,500 g mass that accelerates to a velocity of 10 m/s.
We use the formula F = m × v.
where F = force, m = mass and v = velocity.
In our case m = 1,500g which is 1.5 kg, and v= 10 m/s
F= m × v → F = 1.5 × 10 → F = 15
Therefore the amount of force that was applied to accelerate the object to 10m/s² is 15kg m/s² or 15 Newtons
