Answer:

  • <u>Translated from French language:</u>

"Pierre drives a car at constant speed on a stretch of straight highway. It travels 450 m for a duration equal to 9500 ms. Then, at the same speed, he tackles a turn in an arc. 1. Calculate Pierre's speed in: a) The frame of reference related to the car. B) The road-related frame of reference. 2. What is Pierre's trajectory in the frame of reference linked to the road? 3. Deduce the nature of Pierre's movement in this same frame of reference."

An 80 kg skateboarder moving at 3 m/s pushes off with her back foot to move faster.
Dmitry [639]

Answer:

640 J

640 J

Explanation:

ΔKE = ½ mv² − ½ mu²

ΔKE = ½ m (v² − u²)

ΔKE = ½ (80 kg) ((5 m/s)² − (3 m/s)²)

ΔKE = 640 J

Work = ΔE

Work = 640 J

How would the mathematical model change if the direction that the object traveled was reversed
victus00 [196]
A line that is falling towards the x axis represents an object that is negatively accelerating, or slowing down. When the line hits the x axis, the object has stopped moving. If the graph continues below the x axis, the object has changed direction and is moving backwards at increasing velocity.

During a takeoff run, an aircraft starts from rest and has a lift-off speed of 120 km/h. a. What minimum constant acceleration d
svp [43]

Answer:

1.984 m/s^2

Explanation:

initial velocity of air craft, u = 0 m/s

final speed of the aircraft, v = 120 km/h

Convert the speed into m/s from km/h

So, v = 120 km/h = 33.33 m/s

distance, s = 280 m  

Let a be the acceleration of the aircraft.

Use third equation of motion

v^{2}=u^{2}+2\times a\times s

33.33^{2}=0^{2}+2\times a\times 280

a = 1.984 m/s^2

Thus, the acceleration of the aircraft is 1.984 m/s^2.
