Explanation:
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s)
which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.
Answer:
1.984 m/s^2
Explanation:
initial velocity of air craft, u = 0 m/s
final speed of the aircraft, v = 120 km/h
Convert the speed into m/s from km/h
So, v = 120 km/h = 33.33 m/s
distance, s = 280 m
Let a be the acceleration of the aircraft.
Use third equation of motion


a = 1.984 m/s^2
Thus, the acceleration of the aircraft is 1.984 m/s^2.
A. The restoring force is tripled
