Answer:
work = 500*3 = 1500 J
1500J in 5 sec = 300 watts
Explanation:
Answer:
B. Kinetic energy of the system is partially used up in the deformation of the vehicles.
Explanation:
In an inelastic collision, momentum is conserved, but kinetic energy is not. Kinetic energy is lost as heat or lost in the deformation of the objects.
Given:
m = 13.2 oz, the mass of water measured
Note that
Answer: 0.0284 kg
Answer:
1.29 s
Explanation:
Given:
Δy = 1.40 m
v₀ = 0 m/s
a = 1.67 m/s²
Find: t
Δy = v₀ t + ½ at²
(1.40 m) = (0 m/s) t + ½ (1.67 m/s²) t²
t = 1.29 s
