An airplane travels 4000 in 16 seconds on a heading of 35 degrees. what is its velocity,

A train travels 350 km in 2.5 hours. What was the average speed of the train?

If you slide down a rope, it's possible to create enough thermal energy to burn your hands or your legs where they grip the rope. Suppose a 30 kg child slides down a rope at a playground, descending 1.5 m at a constant speed.

A block slides down a frictionless inclined ramp. If the ramp angle is 12° and its length is 10 m, find the speed of the block as it reaches the bottom of the ramp, assuming it started sliding from rest at the top.

Which of the following choices best represents a potential stressor?

How do you distinguish between speed, velocity, and acceleration?

The force of friction on a sliding object is 10n. the applied force needed to maintain a constant velocity is:
