They are all cardiovascular exercises.
Answer. the curved speed time graph represents the non-uniform accelerated motion.
Newton's second law of motion says
Force = (mass) x (acceleration) .
<span>B. When the net force ACTING ON an object decreases,
the object's acceleration decreases.</span>
Answer
given,

t = 3 s
we know,


position of the particle

integrating both side


Position of the particle at t= 3 s

x = 182.98 ft
Distance traveled by the particle in 3 s is equal to 182.98 ft
now, particle’s acceleration



at t= 3 s

a = 2.98 ft/s²
acceleration of the particle is equal to 2.98 ft/s²
The Battle of the Bulge in the winter of 1944 was the last Great German offensive of the Second World War.
