Answer:
pretty sure the answer is speed walk, hope this helps
Answer:
v = 3.08 m/s.
Explanation:
Given,
- Initial velocity of the block = u = 43 cm/s = 0.43 m/s
- mass of the block = m = 1.40 kg
- spring constant = k = 15.5 N/m.
- x = 0.650 m
At x = 0.650 m
Let 'a' be the acceleration of the block at x.
Total force due to the spring force on the blcok at x= kx
Hence the acceleration of the block at x is 7.19\ m/s^2.
Let 'v' be the velocity of the block at x.
From the kinematics,
Hence at the compression x = 0.650 m the velocity of the block is 3.08 m/s.
Answer:
Answer C : The object's momentum will greatly increase
Explanation:
Recall that force and linear momentum are closely related by the equation:
Both, Momentum Change and Force (F) are in the numerator of on either side of the equation, so they are in direct proportionality. A large force (force greatly increased) will be the reflection of a large change in momentum.
The objects must be in physical contact. Convection is thermal energy transferred by the flow of matter. Radiation is the transfer of energy by electromagnetic radiation. ... 4.3: Thermal conductivity K is a constant indicating how easily heat is transferred through a substance. Sorry if I’m wrong.
