A marble is projected from a card stock catapult at a point 18 cm above the floor. If the marble is given an initial velocity of 8 m/s at an angle of 50° find (a) the time to the maximum height of the marble.
(b) the maximum height of the marble.
(c) the total time the marble is in the air graphically.
(d) the range of the marble.
(e) the final speed when the marble strikes the ground.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
