Answer:

They are inversely related; As acceleration decreases, mass increases; As acceleration decreases, mass increases.

Explanation:

This is to keep the force the same.

F=2m•0.5a

F=0.5m•2a

Both forces have the same value, but they have acceleration and masses that are inversely proportional to eachother.

In real life, you can see it with a recoil gun. The bullet and the gun have equal but opposite forces, but the bullet accelerates faster than the gun due to its smaller mass, while the gun recoils at a slower acceleration due to its larger mass.

A car traveling 91 km/h is 280 m behind a truck traveling 76 km/h.

Olegator [25]

Answer:

speed of car = 95 km/h

speed of truck = 75 km/h

relative speed of car with respect to truck = 95 - 75 = 20 km/h

now we will convert it into m/s

now time to cross the truck will be given as

time = 19.8 s

so it will take 19.8 s to cross the truck

For a vehicle to negotiate a banked curve in poor weather conditions, where the force of friction f = 0, for a given velocity v

djverab [1.8K]

Answer:

$R=240m$

Explanation:

From the question we are told that:

Velocity $v=25m/s$

Force of friction f = 0

Angle $\theta=15$

Generally the equation for Radius of curvature is mathematically given by

$R=frac{v^2}{tan\theta *g}$

$R=frac{25^2}{tan 15 *9.81}$

$R=240m$

What is the proper battery cable connection when jumping two automotive batteries? (a) negative to negative / positive to positi

Vladimir [108]

The proper battery cable connection when jumping two automotive batteries is : (a) negative to negative / positive to positive.

Connect the red (positive) cable from the car with the bad battery to the red (positive) on the good battery. 

Then connect the black (negative) from the good battery to a grounding point on the other car which should be tightened and metal should be clean.

Once the car with bad battery has started, the removal of the cable should be in the opposite order. The Red (positive) which was the the First Cable to go on should be the last cable to be taken off.
