Answer:
20,000 N
Explanation:
First find the acceleration:
a = Δv / Δt
a = (0 − 40 m/s) / 10 s
a = -4 m/s²
Next use Newton's second law to find the force on the car:
F = ma
F = (5000 kg) (-4 m/s²)
F = -20,000 N
According to Newton's third law, the force on the wall is equal and opposite the force on the car.
F = 20,000 N
Hence the expression of ω in terms of m and k is
Given the expressions;
Equating both expressions we will have;
Divide both equations by 2π
Square both sides
Take the square root of both sides
Hence the expression of ω in terms of m and k is
Answer:
Boiling point of water is 100 deg C. It takes about 540 cal to change 1 g of water at the boiling point to 1 g of steam at 100 deg C.
