Go through the intersection without stopping is the appropriate action to be taken in a case where the light at an intersection is red and a police officer directs you to go through it.
<h3>What is Traffic light?</h3>
This is also referred to as stoplights and is present in the intersection of roads etc so as to help control traffic and prevent the occurrences of accidents on the road.
In cases where there is no officer, the traffic light must be obeyed but where the officer is present then his authority overrules and must be obeyed as he is in the best position to know the reason why the traffic light should be ignored in this type of scenario.
This is therefore the reason why the individual should go through the intersection without stopping.

i dont get it so much but
The weight of the bag pack is 8.2 N. g = 1.64 m/s2. Hence, the acceleration due to gravity on moon is 1.64 m/s2. sooo? is it right
Answer:
a) 1.22 s
b) 9.089 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
Time taken by the ball to reach the highest point is 1.22 seconds
The maximum height the ball will reach above the ground is 1.75+7.339 = 9.089 m
Answer:
Explanation:
The equivalent of Newton's second law for rotational motions is:
where
is the net torque applied to the object
I is the moment of inertia
is the angular acceleration
In this problem we have:
(net torque, with a negative sign since it is a friction torque, so it acts in the opposite direction as the motion)
is the moment of inertia
Solving for , we find the angular acceleration:
While he is lifting the dumbell as the definition of work done = moving a mass through a distance = F x d
