Answer
given,
mass of block = m = 2.3 Kg
spring constant = k = 150 N/m
speed = 2.3 m/s
a) we know,
ω = 8.08 rad/s
v = A ω
2.3 = A x 8.08
A = 0.285 m
b) maximum acceleration
a = A ω²
a = 0.285 x 8.08²
a = 18.58 m/s²
c) acceleration is minimum at mean position the minimum value of acceleration is zero.
d) time period
T = 0.778 s
t = 4.1 x 0.7778
t = 3.188 s
Answer:
a)
b) 35m/s
c) 0
d) -35m/s
e) Velocity is decreasing.
f) 70 seconds
If their are choices you should list them. The givens are pretty specific though.
W = E * I is the answer
E (voltage) = W/I is a more refined answer. <<< answer.
The crumple zones in the second car will improve the chance of survival of the driver because it will act as shock absorber, reducing the impact of the force on the driver.
<h3>
Newton's third law of motion</h3>
According to Newton's third law of motion, action and reaction are equal and opposite.
The car with rigid body will exert maximum force to the driver while the car with crumple zone will exert lesser force to the driver since the crumple zone will act as shock absorber, reducing the impact of the force on the driver.
Thus, the crumple zones in the second car will improve the chance of survival of the driver because it will act as shock absorber, reducing the impact of the force on the driver.
