A fighter pilot experiences a force of 1000N to the west. If his mass is 70kg, what is his acceleration

The driver of a car traveling at 110 km/h slams on the brakes so that the car undergoes a constant acceleration, skidding to a complete stop in 4.5 s. which is the most accurate plot of velocity versus time for the braking car?

When you try to stretch a bungee cord a distance x, it resists with an opposing force of the form b x2, where b is a constant. If b is measured to be 6 N/m2, how much work does it take to stretch the bungee cord a distance of 1 meterA. 2JB. 3JC. 0.

A block of 250-mm length and 54 * 40-mm cross section is to support a centric compressive load P. The material to be used is a bronze for which E = 95 GPa.

The maximum current supplied by a generator to a 25 ohm circuit is 6.2 a. What is the rms potential difference?

The ballistic pendulum is an apparatus used to measure the speed of a projectile. An 8.0 g bullet is fired into a 2.5 kg ballistic pendulum bob, which is initially at rest, and becomes embedded in the bob.

What happens to the acceleration of an object is its mass doubles?

The angle a vector makes with the x-axis of a coordinate system must be what size in order to make one or more of its components negative?

How would you calculate power if work is not done?

Equipotential surface A has a potential of 5650 V, while equipotential surface B has a potential of 7850 V. A particle has a mass of 5.40 10-2 kg and a charge of 5.10 10-5 C. The particle has a speed of 2.00 m/s on surface A.
