Answer:
Final velocity of the car will be -9.28 m/sec
Explanation:
We have given that the car starts from the rest so initial velocity of the car u = 0 m /sec
Acceleration of the car 
in negative direction so acceleration will be 
From first equation of motion we know that
v = u+at
So 
So final velocity will be -9.28 m/sec
Answer:(-4,3)
Explanation: They didn’t show the whole graph so it looks confusing but it’s not.
Answer:
v= 335 m/s
2∆t= 0.75 s
∆x= v.∆t → ∆x= 335×½×0.75 = 125.625 m
Answer:
nodding of head ,yes- static equilibrium
nodding of head, no- dynamic equilibrium.
Explanation:
static equilibrium monitors head position when body is not moving .
dynamic equilibrium monitors the angular or rotational movements of the head when body moves.
Answer:
2084 kg*m/s
Explanation:
Impulse is change in momentum
Mathematically;
Impulse, J= F*t=mΔv where
F= ma = 1500 * { 30.56 - 16.67}/2*60
F= 1500 *0.11575
F= 174 N
J=F*t
J= 174*120*0.1
J= 2084 kg*m/s
