A 60-kg man wishes to run on ice. The coefficient of static friction between his shoes and the ice is 0.1. What is his maximum possible acceleration in m/s2?

You place a crate of mass 20.3 kg on a frictionless 2.61-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.01 s after you released it. What is the angle of the incline?     37.7 degrees     31.4 degrees     44.0 degrees     57.2 degrees

A boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided.  Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?

A truck is driving forward with a 90 kg crate on the back. The coefficient of static friction between the crate and truck is µ-0.28. What is the fastest rate the truck could accelerate forward, in m/s², without the crate slipping off the back?

A block is sliding with an initial velocity of 4.0 m/s. If the block suddenly begins to accelerate in the opposite direction with a magnitude of 0.5 m/s2, how far does the block slide before coming to a complete stop?

A car travels west at 30 miles an hour for 10 min West. The car then makes a u turn and travels east 45 miles per hour for fifteen min east. What is the cars total displacement? A- 10km W B-10 km E C- 26 km E D - 26 km W E- 6.2 km W
