A motorcycle stops at a red light and then gains a speed of 12 m/s in 15s. What's its acceleration? 0.8 m/s^2
1.25 m/s^2
-0.8 m/s^2
-1.25 m/s^2

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?
