Answer:
The speed of her at the bottom is 24.035 m/s.
Explanation:
Given that,
Speed of cyclist = 12 m/s
Height = 30 m
Distance d = 450 m
Mass of cyclist and bicycle =70 kg
Drag force = 12 N
We need to calculate the speed at the bottom
Using conservation of energy
K.E+P.E=drag force+K.E+P.E
Potential energy is zero at the bottom.
K.E+P.E=drag force+K.E
Hence, The speed of her at the bottom is 24.035 m/s.
A. 0.25 terabytes
b. 2.5e + 17
This is the definition of specific heat capacity. 1000J of heat are required to raise the temperature of 1kg of the compound by 1 degree. Therefore a 1000J have been added to the block.
