Answer:
the highest point above the ground = 0.48 m
Explanation:
lets ignore air friction, spring details,
The rest mass hanges 0.42 m above the floor and you pull 0.06 m below the original position, this is done by putting energy into the stratched spring so that when released the mass will compress the spring and cover a distance 0.06 m above the rest height.
then the highest point the mass will attain is 0.42 m + 0.06 m = 0.48 m above the ground.
The answer will be: A) Metal washers.
The angle theta of the spring is 31 degrees. To solve for this, show the equation which is equal to the 10lb ball. With this, the unknown will be the angle. Then transpose/transfer the terms in order to isolate the variable for the angle. First solve for s, then solve for angle theta. You will come up with s = .5849 ft and angle theta = 31.2629 or 31 degrees. Hope this helps.
Answer:
The acceleration of Chevy Corvette is
.
Explanation:
Given that,
Initial speed of Chevy Corvette Z06, u = 0 (it starts from rest)
Final speed of Chevy Corvette Z06, v = 60 mph
1 mph = 0.44704 m/s
60 mph = 26.82 m/s
Time, t = 3 seconds
We need to find the acceleration of Chevy Corvette. The rate of change of velocity is called acceleration of an object. It is given by :


So, the acceleration of Chevy Corvette is
. Hence, this is the required solution.
