Apendulum has a mass of 1.5 kg and starts at a height of 0.4 m. if it is released from rest, how fast is it going when it reaches the lowest point of its path? acceleration due to gravity is g = 9.8 m/s2. a. 2.8 m/s b. 0 m/s c. 5.9 m/s d. 4.3 m/s

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another hour will mark brainliest
