Impact and impact force (physical formula) 1) When an object is pulled by a continuous 5kg force, it will accelerate from the static state and stop after hitting a wall The friction on the ground is constant The initial velocity is 0 and the acceleration distance is 0.75m. I want to calculate the velocity at the moment of impact on the wall Thank you. Please give me a formula. I can calculate it later 2) . iron block: 15kg, 50cm from the ground, free fall, impact force to the ground? Thank you. Please list the formula for me

What do you want? An object is subjected to a force of 5kg. At a distance of 0.75m, the final velocity is a = (50-fmo) / m. FMO is the friction force, M is the mass of the object. The final velocity v = radical 2a0.75. The second velocity v = radical 2g50 = radical 1000ft = MV = 15000, t is the impact time, and M is the mass of the object
