A particle moves over the sides of an equilateral triangle if side l with constant speed v

The magnitude of average acceleration is

a cyclist accelerates from 0 m/s to 10 m/s in 3 seconds. what is his acceleration? is the acceleration higher than that of a car which accelerates from 0 to 40 m/s in 8seconds

a ball of mass 0.5 kg moving at 10 m/s collides with another ball of equal mass at rest. if the two balls move off together after the impact calculate their common velocity

What are two ways to increase the acceleration of an object?

Which scenario represents the weakest force? (Assume particles in all scenarios are the same distance apart.) Protons and neutrons are held together inside the nucleus. Two particles are attracted to one another by static electricity.

Does all energy travel in waves

Newtons first law states that no force is required to maintain motion in a straight line at a constant speed. If newtons first law is true, why must we continue to pedal a bicycle on a level surface to keep moving?

A box is lowered using a rope. If the acceleration of the box, is 3.3 m/s2 (downward) and its mass is 29.1 kg, what is the magnitude of the tension in the rope?

Why si system been developed? Give reason.

un objeto se lanza verticalmente hacia arriba con una velocidad de 40 km/h calcular el tiempo que tarda cuando alcanza su altura maxima

A 3.00 watt electric motor is plugged into an electrical outlet It takes the motor 30 00 seconds to lift a mass of 254.9 g a distance of 10.00 cm. In that time, the motor has used 90.
