During that final period of time,
his acceleration is
(9 m/s - 5 m/s) / (4 sec) = 1 m/s² .
Did you have a question to ask ?
Answer:
The relationship between amperage, voltage, and power is that power equals the amperage quantity times the amount of voltage.
Explanation: brainliest pls
Speed= distance/time
Speed= 150000m/7200s=20.83m/s(cor.to.2d.p.)
B. kinetic energy increases and potential energy decreases
Answer:
50 N/m
Explanation:
Elastic energy = kinetic energy
EE = KE
½ kx² = ½ mv²
½ k (4 m)² = ½ (8.0 kg) (10.0 m/s)²
k = 50 N/m
