what is the momentuan of a man of mass
75 kg when he walks with a velocity of
2 m/s ?
the force
required to produce an acceleration of 2 m/s in
a body of mass 12 kg ? what would be the
acceleration it the force were doubled ?

Explanation:
Mass of man (m) = 75 kg
Velocity (v) = 2 m/s
Momentum (p) = ?
- p = m × v
- p = 75 × 2
- p = 150 kg m/s
Acceleration (a) = 2 m/s²
Mass of body (m) = 12 kg
Force (F) = ?
- F = m × a
- F = 12 × 2
- F = 24 N
If the force is double then acceleration will also be double.

Answer:
momentum of any body =m*v
where m is mass of body
v is velocity of the body
so
momentum of man= 75 * 2 kg- m/sec
= 150 N sec
force on a body F= m* a
where m is mass of body
a is acceleration of body
so
F = 12*2 kg m /s^2
F = 24 N eq1
if force get double then the acceleration
2F=12*a using eq1
2*24=12*a
a= 4 m/s^2
