What should you do if your brakes fail? Hook your shoe under the pedal and see if you can free it. Pull the steering wheel back.

Zolol [24]

Answer: Try pumping the brake pedal to increase pressure.

Explanation:

When the brake of a vehicle fails when driving, it's important to pump the brake pedal to increase pressure.

Sometimes, there may be a soft brake due to the fact that the brake master cylinder of the vehicle cannot full pressure which is necessary for the braking power.

One should quickly pump the brake pedal with his or her foot so as to generate enough pressure which will be necessary in stopping safely.

Galina-37 [17]

Answer:

Mathematical physics refers to the development of mathematical methods for application to problems in physics. The Journal of Mathematical Physics defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories".[1] It is a branch of applied mathematics, but deals with physical problems.

10. At point A, a runner is jogging 5 m/s. Forty seconds later, at point B

kondaur [170]

Answer:

Deceleration of 0.075m/s²

Explanation:

Given parameters:

Initial velocity = 5m/s

Time = 40s

Final velocity = 2m/s

Unknown:

The jogger's acceleration = ?

Solution:

To solve this problem, we use;

a = $\frac{v - u}{t}$

a is the acceleration

v is the final velocity

u is the initial velocity

t is the time taken

a = $\frac{2 - 5}{40}$ = - 0.075m/s²

A student sits atop a platform a distance h above the ground. He throws a pingpong ball horizontally with a speed v. However, a

Nikitich [7]

Answer:

Explanation:

The pingpong ball reaches the ground directly under the student. That means net displacement is zero

Time of fall t = $\sqrt{\frac{2h}{g} }$

Initial horizontal velocity = v ,

horizontal acceleration = - a ( deceleration because net displacement is zero)

0 = ut - 1/2 a t²

0 = $v\times\sqrt{\frac{2h}{g} } - \frac{1}{2}a \frac{2h}{g}$

v = 1/2 a $\sqrt{\frac{2h}{g}$

h = $\frac{2gv^2}{a^2}$
