A sport car moving at constant speed travels 110m in 5.0 s. if it then brakes and comes to a stop in 4.0 s, what is the magnitude of its acceleration in m/s2, and in g’s (g=9.80 m/s2)? 2

Answers

d = 110 m, t = 5 s
v o = 110 cs : 5 m = 22 m/s
-------------------------------------
v = v o - a t
v = 0 m/s, v o = 22 m/s, t = 4 s
0 = 22 - 4 a
4 a = 22
a = 22 : 4
a = 5.5 m/s²
g = 9.80 m/s²
9.80 : 5.5 = 0.56
Answer:
The magnitude of its acceleration is 5.5 m/s or 0.56 g.

A 700-watt gasoline engine and a 300-watt electric motor both do 3 J of work. Which machine can do the work faster? Explain your answer.

Answers

700 W gasoline engine do the work faster than electric motor.
What define time of execution of a work is power.
If gasoline engine has 700 W so it is faster than electric motor that has only 300 W

A corvette can accelerate during high speeds at about 2.0 m/s2. At this rate how long does it take the car to accelerate from 80 km/h to 160 km/h? Answer in seconds. Round to two decimal places.

Answers

Answer:

11.11 s

Explanation:

Given:

u = 80 km/h = 22.22 m/s

v = 160 km/h = 44.44 m/s

a = 2.0 m/s²

Find: t

v = u + at

44.44 m/s = 22.22 m/s + (2.0 m/s²) t

t = 11.11 s

suppose you sit on a rotating stool, holding a big mass in each outstretched hand. if you suddenly drop the masses, will your angular velocity increase, decrease, or stay the same? explain.

Answers

Answer:

When the masses drop, they move with the same angular velocity as you before hitting the ground. i.e., they leave your hand with their angular momentum. So, in one view, you can think the mass decreases, which means the moment of inertia also decreases. Therefore, the angular velocity should increase.

Name the physical quantity measured by the velocity-time graph?

Answers

The so-called "velocity-time" graph is actually a "speed-time" graph. At any point
on it, the 'x'-coordinate is a time, and the 'y'-coordinate is the speed at that time.

'Velocity' is a speed AND a direction. Without a direction, you do not have a velocity,
and these graphs never show the direction of the motion. It seems to me that it would be
pretty tough to draw a graph that shows the direction of motion at every instant of time,
so my take is that you'll never see a true "velocity-time" graph.

At best, it would need a second line on it, whose 'y'-coordinate referred to a second
axis, calibrated in angle and representing the 'bearing' or 'heading' of the motion at
each instant. The graph of uniform circular motion, for example, would have a straight
horizontal line for speed, and a 'sawtooth' wave for direction.
