You are travelling at 60.0 mph on the Grand Central Parkway near exit 10 where it is (nearly) parallel to the Long Island Expres

Romashka-Z-Leto [24]

Answer:

a)Vr= 5 mph

b)Vr= 115 mph

Explanation:

Lets

your velocity ,u= 60 mph

velocity of truck ,v= 55 mph

When object are moving in opposite direction the relative velocity = u +v When object are moving in opposite direction the relative velocity = u - v

Truck is moving in the same direction ,so the relative velocity

Vr= = u - v

Vr= 60 - 55

Vr= 5 mph

Truck is moving in the opposite direction ,so the relative velocity

Vr= = u+v

Vr= 60 + 55

Vr= 115 mph

As a football player moves in a straight line [displacement (3.00 mm)i^i^ - (6.50 mm)j^j^], an opponent exerts a constant force

Brilliant_brown [7]

Answer:

Work done, $W=(0.378i-1.092j)\ J$

Explanation:

Displacement,

$d=(3i-6.5j)\ mm\\\\d=(0.003i-0.0065j)\ m$

Force, $F=(126i+168j)\ N$

Work done by the opponent do on the football player is given by :

$W=F{\cdot} d\\\\W=(126i+168j){\cdot} (0.003i-0.0065j)\ m\\\\W=(0.378i-1.092j)\ J$

So, the work done by the opponent do on the football player is $(0.378i-1.092j)\ J$ .

In a race, a runner traveled 12 meters in 4.0 seconds as she accelerated uniformly from rest. The magnitude of the acceleration

mestny [16]

The runner is moving by uniformly accelerated motion, starting from rest (so, his initial velocity is zero). The law of motion of the runner is
 $x(t) = \frac{1}{2} at^2$ 
where x(t) is the distance covered after time t, and a is the acceleration of the runner. By re-arranging the formula, we get
 $a= \frac{2S}{t^2}$ 
We know the runner has covered a distance of S=12m in t=4.0 s, and if we plug these numbers into the equation, we find the acceleration of the runner:
 $a= \frac{2S}{t^2} = \frac{(2*12m)}{(4s)^2} =1.5 m/s^2$
