Answer:
The correct option is;
Neither A nor B
Explanation:
The common cause of a vehicle pulling to the right or to the left during braking is due to a contaminated breaking surface or a faulty caliper. Other causes include tire size variation or worn out suspension components.
Other causes include;
Leaking break fluid
Piston frozen in wheel cylinder or caliper
Adjuster of rear break
Tire fault.
As soon as it is observed that the vehicle pulls on one side when braking, the vehicle should should be taking for checks by a qualified mechanic as soon as possible.
The x-component of the acceleration is
Explanation:
This problem is an example of uniformly accelerated motion, so we can solve it by using the following suvat equation:
where
u is the initial velocity
a is the acceleration
s is the displacement
t is the time
For the body in this problem, we have:
u = 11.1 cm/s is the initial velocity
The displacement is
s = -3.58 - (3.59) = -7.17 cm
While the time is
t = 2.48 s
Substituting and solving the formula for a, we find the x-component of the acceleration:

Answer:
a. s = 0.96 m
b. s = 2.15 m
Explanation:
a.
The relationship between the linear displacement and the angular displacement is given as follows:
where,
s = linear distance covered = ?
r = radius of wheel = (6 in)(0.0254 m/1 in) = 0.1524 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,
<u>s = 0.96 m</u>
<u></u>
b.
Assuming, we have to find linear displacement here, as well:
where,
s = linear distance covered = ?
r = radius of wheel = (13.5 in)(0.0254 m/1 in) = 0.3429 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,
<u>s = 2.15 m</u>
V= s/t = 400/4.5=800/9 (km/h)
Solution :
A vector is defined as an element that has magnitude of some measure and direction.
It is given there is vector 'd' which has magnitude 2.6 m and its direction is towards north.
a). -d
The magnitude of the vector '-d' is 2.6 m and its direction is reversed, i.e. its direction is towards south.
b). d/2.0
The magnitude of the vector 'd/2.0' is 1.3 m and its direction is towards north.
c). - 2.5d
The magnitude of the vector increases by 2.5 times i.e. 2.5 x 2.6 = 6.5 m and the direction is towards south.
d). 5.0d
The magnitude of the vector increases by 5 times i.e. 5 x 2.6 = 13 m and the direction is towards north.
