NEWTON'S SECOND LAW OF MOTION

A 0.05KN ball is placed on a vertical circle whose length of the cord is 1.80m. Compute the height (m) measured from the lowest position that the ball will rise on the circular path if the maximum tension the cord can hold is 0.20KN. *.A car is entering a curve of radius 190m with a veiocity oi 165kph. Determine the angle of banking of the track to prevent the 1435kg car from sliding down the track The coefficient of friction between the tires and the track is 0.30
