Part A A 20.0 kg projectile is fired at an angle of 60.0∘ above the horizontal with a speed of 80.0 m/s. At the highest point of its trajectory, the projectile explodes into two fragments with equal mass, one of which falls vertically with zero initial speed. Ignore air resistance. How far from the point of firing does the other fragment strike if the terrain is level? Express your answer with the appropriate units. Submit Request Answer Part B How much energy is released during the explosion? Express your answer with the appropriate units. ΔE = Value Units

QUESTION 05 (a) (i) What is meant by kinetic energy? (ii) What is the relationship between potential and kinetic energy? (b) (i) Explain Hooke's law? What is restoring force? (ii) What is conservation of energy? (c) In Figure, a single frictionless rollercoaster car of mass m = 825 kg tops the first hill with speed v0 = 17.0 m/s at height h = 42.0 m. How much work does the gravitational force do on the car from that point to (i) point A, (ii) point B, and (iii) point C ? If the gravitational potential energy of the car-Earth system is taken to be zero at C, what is its value when the car is at (iv) B and (v) A? (vi) If mass m were doubled, would the change in the gravitational potential energy of the system between points A and B increase, decrease, or remain the same?

You throw a 0.374 kg ball off the top of a 13.0 m tall building with an initial angle of 30.0∘ above the horizontal. The ball rises to a maximum height of 18.6 m before falling back to the ground. How much work does gravity do on the ball from the point you release the ball until it hits the ground? 47.6 J −47.6 J −68.2 J 68.2 J
