Answer:
431.83 N/m
Explanation:
Applying the law of conservation of energy,
From the question,
The kinetic energy of the plunger = energy stored in the spring
1/2mv² = 1/2ke²...................... Equation 1
Where m = mass of the plunger, v = velocity of the plunger, k = spring constant of the spring, e = compression.
make k the subject of the equation
k = mv²/e².......................... Equation 2
Given: m = 0.05 kg, v = 26.3 m/s, e = 0.283 m
Substitute into equation 2
k = 0.05(26.3²)/0.283²
k = 34.5845/0.080089
k = 431.83 N/m
Answer:
147 N
Explanation:
static friction = frictional force max / normal
normal force = mg = 50 kg × 9.8 m/s² = 490 N
0.3 = Frictional force / 490 N
0.3 × 490 N = 147 N
The body will not move because the frictional force is greater than the force applied.
Answer:
10.66mm
Explanation:
Given that the elongation is and Length, and Tensile Strength,, The longitudinal stress can be calculated as:
The value of strain-stress, corresponding to '
Hence, the radius of the specimen is 10.66mm
Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed. Hope you find this helpful
Answer:
if it is not moving it is zero, like all things that aren't in motion
