The average force necessary to stop a hammer having momentum 25N-s in 0.05 second is
BrainlyHulk:
Momentum unit is not Ns
It is kgm/s
its unit also ns coz momentum also equel to force×time
No it is impulse
read theory again..
momentum = impulse., which is fdt. and force is equel to dp/dt

remind relation of force and momentum will make it easy
Attachments:
momentum also equel to product of force and time now comes unit N-Sec bro.

Average Force = Rate of change of momentum
= (Final Momentum - Initial Momentum) / Time
= (25 - 0) / 0.05
= 500 N
Average Force required is 500 N
= (Final Momentum - Initial Momentum) / Time
= (25 - 0) / 0.05
= 500 N
Average Force required is 500 N
