A car jumps off a ramp with a Kinetic energy of 5,000 joules. This same car has a gravitational potential energy of 4,685 joules at some point when it is falling to the
ground, after jumping off the ramp. When the car lands on the ground, the springs of
this car's suspension compress and then come back to normal exerting an elastic
potential energy of 4,968 joules.
What is the car's total mechanical energy (TME)?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

What is created when solids,liquids,an gases mix with one another

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
