A car travelling at 45 mi/hr (20.1 m/s) comes to rest in 4 seconds. Find the acceleration of the car in m/s2.

Select the higher harmonics of a string fixed at both ends that has a fundamental frequency of 80 Hz.

In a spring gun, a spring of mass 0.240 kg and force constant 3100 N/m is compressed 2.00 cm from its unstretched length. When the trigger is pulled, the spring pushes horizontally on a 5.5*10-2 kg ball. The work done by friction is negligible.

If two forces 3N and 20N acts on a body of mass 15kg, find the acceleration

Which characteristic of a sound wave is directly related to the loudness of the sound? a (amplitude b (pressure c (wavelength d (frequency

car A start 10 meters ahead of car B. Car A moves at v = (3.0i+0j) m/s and car B moves forward at v = (7.0i+0j) m/s how many seconds does it takes car B to catch up

Definition of mechanical weathering

If you double the force of an object what happens to the acceleration?

A particle (mass - 5 g. charge 30 mC) moves in a region of space where the electric field is uniform and is given by Ex 4.8 N/C, Ey-E. 0. If the velocity of the particle att-O is given by v,-40 m/s V, v-0, what is the speed of the particle at t3 s?

When the Egyptians noticed this celestial body rising before the Sun it indicated to them the coming of the Nile flood.
