A tennis ball is lightly thrown vertically upwards to be struck by the racquet at the peak of the trajectory of the ball. A 350 g tennis racquet hits the ball with a velocity of 30. m⋅s−1. Both racquet and ball move with a horizontal velocity of 25 m⋅s−1 immediately after the collision. What is the mass of the ball, in grams?

this a false

explanation:

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
