Answer:
When a force acts on an object over a distance, it is said to have done work on the object. Physically, the work done on an object is the change in kinetic energy that that object experiences.

Answer:
a=-1.58 m/s^2
Explanation:
Vo=34m/s
Vf=15m/s
t=12s
a= dV/dt = (Vf-Vo) /t = (15-34)/12
= - 19/12 = - 1.58m/s2
The catalyst lowers the activation energy.
Answer:
107 m
Explanation:
Convert km/h to m/s:
128.4 km/h × (1000 m / km) × (1 h / 3600 s) = 35.67 m/s
Distance = rate × time
d = 35.67 m/s × 3.0 s
d = 107 m
