A car is traveling at 100 km/h when the driver sees an accident 80 m ahead and slams on the brakes. what minimum constant decele
Effectus [21]
Assuming the driver starts slamming the brakes immediately, the car moves by uniformly decelerated motion, so we can use the following relationship
2aS = v_f^2 - v_i^2 (1)
where 
a is the deleceration
S is the distance covered after a time t
v_f is the velocity at time t
v_i=100 km/h = 27.8 m/s is the initial speed of the car

The accident is 80 m ahead of the car, so the minimum deceleration required to avoid the accident is the value of a such that S=80 m and v_f=0 (the car should stop exactly at S=80 m to avoid the accident). Using these data, we can solve  the equation (1) to find a:
a=- \frac{v_i^2}{2 S}= -\frac{(27.8 m/s)^2}{2 \cdot 80 m} =-4.83 m/s^2
And the negative sign means it is a deceleration.

A box of groceries requires 5.0 newtons of force to lift it up 1.0 meter. How much work is done?
tigry1 [53]
Work is defined as the amount of force done multiplied by the distance it was applied. Since it is already given that the object of interest (a box of groceries) was lifted up 1 meter by a force of 5 newtons, work done can be solved using the following formula:

Work = Force * distance
Work = 5 N * 1 meter
Work = 5 N*m = 5 J

What is the displacement of an airplane that takes off and ascends 10,000 feet in the air but, to avoid turbulence, descends dow
sladkih [1.3K]
I think it’s A because ascending means going up 10,000 then descending is going down 2,000 so in all they are 8,000 feet above the ground
