A 50kg object accelerates a 5m/s/s. What is the net force acting on the object?

What is the normal acceleration of a car?

When you are running, there is friction between your feet and the ground and air resistance between your body and the air.

Suppose our experimenter repeats his experiment on a planet more massive than Earth, where the acceleration due to gravity is g=30 m/s2.

An automobile accelerates from rest at 1 + 3 * sqrt (t) mph/sec for 9 seconds. how far does it travel in those 9 sec?

A glass lens, n glass = 1.52, has a 131 nm thick antireflective film coating one side, n film = 1.25. White light, moving through the air, is perpendicularly incident on the coated side of the lens.

An automobile steering wheel is shown. The ideal mechanical advantage of this wheel and axle is. If a driver must exert a force of 2 N to overcome an axle resistance of 16 N, the AMA of the steering wheel is and its efficiency is__ %.?

How does the law of conservation of energy apply to machines? -Machines create energy from scratch. -Machines consume energy until no energy remains. -Energy transferred to a machine equals energy transferred from it.
