What force is required to give an object with mass 50 kg an acceleration of 8 m/s2?

An electric car accelerates for 9.9 s by drawing energy from its 340-V battery pack. During this time, 1700 C of charge pass through the battery pack. Find the minimum power rating of the car

A 6.0-kg block initially at rest is pulled to the right along a frictionless, horizontal surface by a constant horizontal force of magnitude 12 N. Find the block's speed after it is has moved through a horizontal distance of 3.0 m

A 93 kg man holding a 0.653 kg ball stands on a frozen pond next to a wall. He throws the ball at the wall with a speed of 11.3 m/s (relative to the ground) and then catches the ball after it rebounds from the wall.

Two ways of defining velocity

A 20.0-kg rock is dropped and hits the ground at a speed of 90.0 m/s. Calculate the rock's gravitational potential energy before it was dropped. (Ignore the effects of friction.)

How are Saturn and Uranus similar? Neither planet has a tilted axis. They both rotate backwards. They both have rings. They are both found inside the asteroid belt.

What physical property makes the red light different from blue light, or radio waves different from microwaves?

describes how the color and texture of a surface affect absorption and reflection of solar radiation?

What does infrastructure refer to? process by which a nation improves the economic, political, and social well-being of its people level of farming in which a person raises only enough food to feed his or her family services and facilities necessary

Sophee left her house on her bike and traveled 3 kilometers north, 5 kilometers east, 3 meters south, then 5 meters west arriving home in time for dinner. What is her distance and displacement?
