a force act on of a mass 20gm . the velocity of the particles changes from 15 m/s to 25m/s in 2.5 . assuming the force to constant . find its magnitude. ?? please help me i mark as brainlist who give ans now

Answer:
Force is mass times acceleration and has units of kilogram-metres per second per second (kg⋅m/s square), also known as Newtons.
The acceleration is the change in velocity over time.
The change in velocity is 25m/s−15m/s=10m/s.
Thus the acceleration is 10m/s/2.5s=4m/s square.
Now you just need to multiply that by the mass in kilograms: 4m/s square X 0.2kg=0.8kg/ms SQUARE=0.8N
