Acar is traveling in a circular curve on a horizontal road at constant speed. name the force that is responsible for causing its circular motion? a the gravity force b the normal force from the road c the friction force from the road d the tension force

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

The speed of light can be used to measure the
