Question

Which would require a greater force:-
(a) accelerating 4 kg mass at 10m/s2 or 8 kg mass at 4 m/s2
(b) Define momentum. MXWT​

Answer 1

Answer:

the force that makes something move faster and faster is called momentum.

Answer 2

A)F=ma

m=4 kg

a=10 m/s^2

F=40 N

F=ma

m=8 kg

a=4 m/s^2

F=32 N

4 kg mass at 10 m/s^2 will require more force

B) Momentum is product of mass and velocity

p=mv
