A car travels along a straight line at a constant speed of 56.0 mi/h for a distance d and then another distance d in the same di

rection at another constant speed. The average velocity for the entire trip is 33.5 mi/h. (a) What is the constant speed with which the car moved during the second distance d?
I started out with Vxavg=(Vxi+Vxf)/2 and came out to 11 and it was wrong. If anyone has a good website I can use to learn physics it would be much appreciated.

2* v1 * v2 / (v2+v1) = V avg2*56* v2 / (v2+56) = 33.5
v2 = 23.94 m/s

Why might a balloon, that is inflated almost to its capacity, pop or explode on an extremely warm day?
REY [17]
On an extremely warm day, the balloon might pop because gases expand the hotter they get, and due to its temperature it is likely to pop if it is, indeed, nearly, if not completely, filled to its capacity.  I hope this helps, have a nice day!

Which three terms are needed to describe the energy a BASE jumper has as she falls toward the ground?
Thepotemich [5.8K]

Answer:

Potential energy

Kinetic energy

Gravitational energy.

Explanation:

The potential energy is the stored energy, it is the energy and object posses at rest. When the base jumper is still at rest i.e without motion, she has potential energy.

Gravitational energy this refer to the potential energy an object or body with mass posses in relation to another object due to gravity.

This is seen when the base number is still at rest and the force of gravity on the Earth acting on her.

Kinetic energy is the energy posses by an object or body in motion.

As the base jumper falls to the ground, she posses kinetic energy which is the energy in motion.
