You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 12-m-high hill, then descends 15 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.1 m and that a loaded car will have a maximum mass of 400 kg. For safety reasons, the spring constant should be 12% larger than the minimum needed for the car to just make it over the top. ▾ ▼ Part A What spring constant should you specify?

A box is pressed against a horizontal spring, compressing the spring from its relaxed length. The box is then released and the spring launches the box horizontally along a track that ends in a ramp, as shown above. The box has enough speed to leave the ramp, and the box reaches a maximum vertical height above the floor. Assume there is negligible friction between the box and the track and air resistance is negligible. K = spring constant of spring X = distance the spring is compressed M = mass box Theta = angle of ramp from horizontal H = maximum height reached by box The scenario is repeated using a different box with a greater mass. The spring is compressed the same distance x. Indicate how h in this second scenario compares to h in the original scenario, and explain why without mathematically deriving a relation for h. Students derive an equation for h in the original scenario, h= (sin2theta)kx2/2Mg, which may or may not be correct. Is this equation consistent with your claim…
You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 10-m-high hill, then descends 17 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.5 m and that a loaded car will have a maximum mass of 400 kg.

An m = 12.0kg block is released from rest on a frictionless incline that makes an angle of 0 = 27.0°, as shown in the figure. Below the block is a spring that has a spring constant of 1.55 × 10¹ N/m. The block momentarily stops when it compresses the spring by 5.50 cm. How far I does the block move down the incline from its release point to the stopping point? Answer in units of centimeters. m eeeeeee 0
How far the block will compress the spring after fall back from its maximum height?
What should be the spring constant kk of a spring designed to bring a 1300 kg car to rest from a speed of 85 km/h so that the occupants undergo a maximum acceleration of 5.0gg? Express your answer using two significant figures.

The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists find that (on average) the knee extensor tendons in sprinters stretch 42 mm while those of nonathletes stretch only 35 mm. The spring constant of the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes? Express your answer to two significant figures and include the appropriate units. ► View Available Hint(s) AU = μA Value N m
An 2.1 kg object is launched down a frictionless ramp at 7.2 m/s towards a spring connected to the bottom end of the ramp. The ramp is 44.8 m long and is angled at 48.4o above the horizontal. The spring constant for the spring is 1770 N/m. By how much is the spring compressed by the object? Round final answers to 2 decimal places.
A spring loaded toy dart gun shoots a dart straight up in the air and the dart reaches a maximum height of 22.90 m. The same dart is shot straight up a second time but this time the spring is compressed only half as far. How far up in meters does the dart go this time neglecting friction? Write your answer to 2 decimals. Your Answer: Answer
It's your birthday, and to celebrate you're going to make your first bungee jump. You stand on a bridge 105 m above a raging river and attach a 30-m-long bungee cord to your harness. A bungee cord, for practical purposes, is just a long spring, and this cord has a spring constant of 48 N/m. Assume that your mass is 70 kg. After a long hesitation, you step off the bridge.How far are you above the water when the cord reaches its maximum elongation?
a cannonball with a mass of 6.95 kg is placed in a vertical, spring-loaded cannon bearing a spring with a spring constant of 5.6 newtons/meter. The spring is compressed by a distance of 4.54 meters and released. Please use g=9.80 m/s2. The max height reached by the cannonball in meters is?
