Answer:
-4.8 m/s²
Explanation:
Apply Newton's second law:
∑F = ma
F − mg = ma
300 N − (60 kg) (9.8 m/s) = (60 kg) a
a = -4.8 m/s²
The acceleration five seconds after jumping is 4.8 m/s² downward.
Given:
mass is 3.1 kilograms
The acceleration due to gravity
is 9.8m/s2
Required:
Weight
Solution:
W = mg
W = (3.1 kilograms)( 9.8m/s2)
W = 30.38 Newtons
I believe the answer that you're looking for is temperature probe. As you raise the heat of the metal cylinder by a specific, measured number of degrees Celsius, you also record the amount of energy put out by the heat source. Specific heat of a substance is equal to the amount of energy or heat needed to raise a substance by one degree Celsius. Use the equation Q=cmΔT, where Q is heat/energy added, c is the specific heat, m is the mass of the cylinder, and ΔT is the change in temperature of the cylinder.

Answer:
A bomb that is dropped from a moving helicopter doesn't fall directly downward rather it follows the parabolic path as it were thrown horizontally from a height with certain initial velocity. Therefore, the bomb should be dropped from farther distance equal to the horizontal range before the helicopter reaches above the target.
