Aspaceship at rest relative to a nearby star in interplanetary space has a total mass of 2.60 ✕ 104 kg. its engines fire at t = 0, steadily burning fuel at 76.0 kg/s with an exhaust speed of 4.50 ✕ 103 m/s. calculate the spaceship's acceleration at t = 0, mass at t = 115 s, acceleration at t = 115 s, and speed at t = 115 s, relative to the same nearby star.

(a) acceleration at t = 0 (enter the magnitude. enter your answer in m/s2.)
(b) mass at t = 115 s (enter your answer in kg.)
(c) acceleration at t = 115 s (enter the magnitude. enter your answer in m/s2.)
(d) speed at t = 115 s (enter your answer in m/s.)

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
