In his first attempt, a long improve food from this spring board with a speed of 8m/s at 30°C tothe horizontal. He makes a secondattempt with the same speed at 45 °C to the horizabal . Given that the expression for the horizontal range of the projectile is U²sin²tintan/g where all the symbols have their usual meanings, show that he gain a distance of 0.8576m in his second attempt.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
