Answer:
the blue bumper car
Explanation:
because the yellow bumper car is coming in with much more force
and according to Newton, actions and reactions are equal and opposite, so the yellow bumper car will five out 300N while the blue car will give out only 100N
then it almost because a fight between 300N vs 100N
and obviously, the 300N will win and the 100N will be pushed back

Answer:
35.6 s
Explanation:
The power through the resistor is given by:
where V=9.0 V is the voltage and I=0.50 A is the current. Substituting into the formula, we find
The power is also equal to:
where W is the work done while t is the time taken. Since we know the work done, W=160 J, we can re-arrange the equation to find the time taken:
Answer:
495.5 Joules
Explanation:
Given data
Mass= 10kg
Height= 5meters
g= 9.81m/s^2
Yes the rock will possess potential energy before it hits the ground
The potential energy is expressed as
PE=mgh
substitute
PE= 10*9.91*5
PE= 495.5 Joules
