Problem # 1
The head of a hammer with a mass of 1.2Kg is allowed to fall onto a nail from a height of 0.50 m. What is the maximum amount of work it could do on the nail?
Problem # 2
How much work did the movers do 9horizontally) pushing a 46 – Kg Crate 10.3 meter across a rough floor without acceleration. If the effective coefficient of friction was 0.50
Problem # 3
On a smooth surface, a soft 100-grams ball A at the velocity of 10 meters per second collides with another 700-grams ball B initially at rest. After collision, the two balls stick together and keep moving in the same direction as ball A. What is the velocity of the two balls after collision?
Problem # 4
A griding wheel 0.35m in diameter rotates a 2200 RPM (angular velocity 230 rad/Sec). Calculate the acceleration of a point on the edge of griding wheel.
Problem # 5
A 200 – g object is tied to the end of a cord, and it is turning in horizontal circle of radius 1.20 Cm at the constant 3 rev/sec. Calculate the centripetal acceleration of the object.
Problem # 6
Calculate the maximum speed of a 1200 – Kg car which round a radius of 90 m on a flat road if the coefficient of friction between tires and road is 0.65?
Problem # 7
A box is given a push so that it slides across the floor. Given that the coefficient of kinetic friction is 0.15 and the push imparts an initial speed of 35 m/s. determine how far will it go?
