13. a catapult launches a boulder with an upward velocity of 148 ft/s. the height of the boulder (h) in feet after t seconds is given by the function h = –16t² + 148t + 30. how long does it take the boulder to reach its maximum height? what is the boulder’s maximum height? round to the nearest hundredth, if necessary.
a) 9.25 s; 30 ft
b) 4.63 s; 640.5 ft
c) 4.63 s; 1,056.75 ft
d) 4.63 s; 372.25 ft

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
