Essay

Give the correct answer

1. An object moves is astraight line with aspeed of 5 m/s. After

traveling 75 km, thespeed becomes 10 m/s.Calculate theacceleration.

2. The linear velocity of apoint which is moving ina circular path with

frequency of 2 Hz is 2m/s. What is thedistance of that point

from the center of path?

3. A ball of 0.5 mass kg istied to a 1 m rope. Thenit is revolvedhorizontally. If the ropecan withstand amaximum tension of 50newtons, what is theballs speed before the

rope breaks?4. A car moves

horizontally with aspeed of 40 km/hour.The frictional coefficientbetween the road and

the tire s = 0.7. What isthe distance required tostop the car, supposethere is no slip between

the tire and the road,and g = 10 m/s2?

5. An object moves on aplane with 10 m/sspeed. If the kinetic

friction coefficient k =0.4 and g =10 m/s2,

determine the distancewhich must be coveredbefore the object stops.
