A 4.4-cm c m -diameter, 24 g g plastic ball is attached to a 1.2-m m -long string and swung in a vertical circle. The balls speed is 6.7 m/s m / s at the point where it is moving straight up. find the magnitude of the net force on the ball. air resistance is not negligible.

48.97N

Explanation:

The magnitude of the net force on the string is expressed as

F = mv²/r

m is the mas of the object = 24 g = 0.024kg

v is the velocity = 6.7m/s

r is the radius = diameter/2 = 4.4/2

radius r = 2.2cm = 0.022m

Substitute the given values into the formula;

F =  0.024(6.7)²/0.022

F = 0.024(44.89)/0.022

F = 1.07736/0.022

F = 48.97N

Hence the magnitude of the net force on the ball is 48.97N

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
