Answer:
force = 11.33 
Explanation:
given data:
sled mass = 17.0 kg
inital velocity (U) = 4.10 m/s
elapsed time (T) 6.15 s
final velocity (V) = 0
final momentum P2 = 0
Initial momentum of sledge is


from newton second law of motion


Kgm/s^2

C. Negative force. The dog isn't going to learn that way.
The correct answer to go in the blank would be A) The particles are moving faster.
Answer:
Ocean waves, sound waves, and light waves.
Explanation:
Answer:
v = 94m/s
Explanation:
Using the first equation of motion
v = u + at
u = 4m/s , a = 3m/s² , t = 30s , v = ?
v = u + at
v = 4 + 3 × 30
v = 4 + 90
v = 94m/s
