Gaurav Seth 7 years, 1 month ago

Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.
it formula = mass × velocity
so it's SI unit is = kg×m/s = kg m/s

Gaurav Seth 7 years, 1 month ago

Optimum speed = v₀ = [RgtanΘ]¹⁻₂

R= 300
theta = 15⁰
g= 10

so, v₀= √300 x 10 x tan 15
= 28.06 ms⁻²

2. max speed= Vm= √Rg u+tan theta/ 1- utan theta
as u=0.2

= √300 x 10 0.2+tan15/1- 0.2tan 15

= 38.13 ms⁻¹

Simran Sian 7 years, 1 month ago

Newton second law is real law of motion because we can derive Newton 1st law from Newton third law. To prove first law: We know, F=ma If no force act on Body So, F=0 ma=0 =>a=0/m 0=a OR a=0 It indicates either body is at rest or moving with constant speed which is first law of motion To prove third law:- F=dp/dt___1 Let f' is acting on 2nd body:- f'=dp'/dt____2 Add 1 and 2: F+F'=dp/dt+dp'/dt F+F'=d/dt(p+p') F+F'=d/dt(constant) F+F'=d/dt(0) F+F'=0 F=-F' Hence, action and reaction are equal and opposite direction
