Question

On a horizontal road, a car is traveling West at a constant speed of 12.0 m/s. After 52 s, it has rounded a corner and is now heading North at a constant speed of 22.8 m/s.

What is the magnitude of the car's average acceleration during this 52 ss time interval?

Answer #1

The initial velocity of the car is 12.0 m/s along west.

East is along positive X-axis and North is along positive Y-axis.

The time interval for the change in velocity is t = 52 s

The final velocity of the car is 22.8 m/s along north.

The average acceleration is

=>

The magnitude of car's acceleration is

**a = 0.5 m/s2**

On a horizontal road, a car is traveling West at a constant
speed of 7.60 m/s After 32 s , it has rounded a corner and is now
heading North at a constant speed of 12.9 m/s. What is the
magnitude of the car's average acceleration during this 32 s time
interval?

On a horizontal road, a car is traveling West at a constant
speed of 11.4 m/s . After 16 s , it has rounded a corner and is now
heading North at a constant speed of 16.0 m/s .
What is the magnitude of the car's average acceleration during
this 16 s time interval?
0.29 m/s2
1.2 m/s2
0 m/s2
1.7 m/s2

A car is traveling west at 22.5 m/s when it turns due south and
accelerates to 25.0 m/s, all during a time of 8.00 s. Calculate the
magnitude of the car's average acceleration (in
m/s2).

A car travels around a horizontal circular driveway at a
constant speed of 4 m/s. Which one of the following statements is
correct? 1.) The car's acceleration is zero. 2.)The car's velocity
is constant but not zero. 3.)The car's acceleration is not zero.
4.)The car's position vector relative to a fixed origin is
constant. 5.)The car's velocity is zero.

A car is traveling at 15 m/s on a horizontal road. The brakes
are applied and the car skids to a stop in 4.0 s. The coefficient
of kinetic friction between the tires and road is:
Select one:
a. 0.38
b. 0.69
A ball is thrown straight up with a speed of 36.0 m/s. How long
does it take to return to its starting point?
Select one:
a. 7.20 s
b. 10.2 s
c. 14.7 s
d. 11.0 s
e....

Suppose you have a car traveling down the road at constant
speed and not changing direction. It is experiencing gravity, wind
resistance and frictional forces from the road. What can be said
about the car's acceleration?
Group of answer choices
It is not accelerating because it has constant velocity.
It accelerating because the motor is running, propelling the
car forward.
It is accelerating because there are forces acting on
it.
It is not accelerating because gravity holds it down.

A car starts from rest, after 10 s the speed of the car is 25
m/s. What is the magnitude of the car's acceleration?

A car is traveling along a straight road at a velocity of +35.0
m/s when its engine cuts out. For the next ten seconds the car
slows down, and its average acceleration is a1. For the next five
seconds the car slows down further, and its average acceleration is
a2. The velocity of the car at the end of the fifteen-second period
is +24.2 m/s. The ratio of the average acceleration values is a1/a2
= 1.78. Find the velocity of...

A car with a mass of 1,400 kg and a speed of 15 m/s heading
north approaches an intersection. At the same time, a minivan with
a mass of 1,800 kg and speed of 22 m/s heading east is also
approaching the intersection. The car and the minivan collide and
stick together. What is the velocity of the wrecked
vehicles just after the collision? Ignore friction between
the tires and the surface of the road. (Enter the magnitude
in m/s...

A car traveling at a constant speed of 21.0 m/s passes a trooper
hidden behind a billboard. One second after the speeding car passes
