A tou car is rounding a circular track with a radious of 1.50 m. The car goes around the track once in 20.0 seconds

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

What property is a characteristic of a substance that can be observed and does not change the identity of the substance

Aball is thrown straight up into the air with a speed of 21 m/s. if the ball has a mass of 0.1 kg, how high does the ball go? acceleration due to gravity is g = 9.8 m/s^2. a. 22.5 m b. 20.0 m c. 25.0 m d. 17.5 m
