What is the average amount of energy of motion in the particles of a substance

Suppose a rocket ship in deep space moves with constant acceleration equal to 9.8 m/s2, which gives the illusion of normal gravity during the flight.

Five race cars speed toward the finish line at the Jasper County Speedway. The table lists each car's speed in meters/second.

A ball of mass 2 kg fallsfrom a rof that is 5 m above the ground. How much gravitational potential energy did the ball lose when it reached the ground, in units of joules? give your answer as a positive value

How long is one day on earth

An archer defending a castle is on a 15.5 m high wall. He shoots an arrow straight down at 22.8 m/s. How much time does it take to reach the ground?

Four potential forces can act on the ball Which combination of forces will keep the ball in static equilibrium? The length of the arrows represents the magnitude of the force A and B A and C B and D 8. Cand D Submit Force, Mass, and Motion

The resultant of a 50N force acting on an object to the right and a 20N force acting on the object to the left is what

A student conducts and investigation to determine a ball's mass, displacement, velocity and acceleration. (A) Identify each of the following as wither a vector or scalar quantity: Mass, Displacement, Velocity & Acceleration.

A ball is rolling down a hill at + 1.0 m/s, The ball is uniformly accelerating at +4.9 m/s?, What will the ball's velocity be 4.0 s later? +8.9 x 100° m/s +2.0 x 10^1 m/s +2.1 x 10^1 m/s -1.9 x 10^1 m/s
