Filip is riding his skateboard and decides to coast and let the friction bring him to a stop. If he decelerates at a rate of -0.145 m/s2 for three quarters of a minute before
coming to a stop, then how fast was he initially traveling?
a
6.53 m/s
b
0.109 m/s
-6.53 m/s
d
-0.109 m/s
e
293.6 m/s
f
-293.6 m/s

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

a sonic boom is a loud boom that breaks the sound barrier

explanation:

the components of a vector are the parts of the vectors that are to each other.
