Find its acceleration:A 10 kg block on rough horizontal surface with μ_s = 0.3 just starts moving. Force applied:A block of mass 2 kg on a smooth incline at 30°. Acceleration down the incline (g = 10):A 1500 kg car accelerates from 0 to 30 m/s in 10 s. Average force on car:In a tug-of-war, team A pulls with 200 N, team B pulls oppositely with 250 N. The rope (light) experiences netNewton's THIRD law pair: when you push a wall, the wall pushes you. These forces:A block of mass 5 kg on a rough incline at 37° with μ_k = 0.4.

Determine if it stays at rest (g = 10, sin 45° = cos 45° = A 4 kg mass hangs from a spring scale in an elevator. Spring reads 32 N. The elevator is:A 3 kg block is pulled with F = 20 N at 30° above horizontal on rough surface (μ_k = 0.4). Find acceleration (In a uniform circular motion, the SPEED is constant but velocity changes direction. The acceleration:A car turns a corner of radius 50 m at 20 m/s.
