a force of 6N acts on a 2kg trolley and accelerates at 2m/s calculate the retarding force acting on the body

Force = rate of change of momentum = m * a if mass is constant

6 - F = 2 kg * 2 m/s^2
F = 6 -4 = 2 Newtons

Did you know?

Did you know that when a force of 6 Newtons acts on a 2-kilogram trolley, and the trolley accelerates at a rate of 2 meters per second, we can use this information to calculate the retarding force acting on the trolley? The formula to calculate force is F = ma, where F represents force, m represents mass, and a represents acceleration. In this case, the force acting on the trolley is 6N, the mass is 2kg, and the acceleration is 2m/s. By rearranging the formula, we find that the retarding force acting on the trolley is equal to the mass multiplied by the acceleration (F = ma). Therefore, the retarding force in this situation would be 4N (2kg × 2m/s). Understanding the relationship between force, mass, and acceleration can help us analyze and predict the behavior of objects in motion.
