solve the distance it travels @ 5 seconds.

Homework Statement A 0.525kg ball starts from rest and rolls down a hill with uniform acceleration, traveling 200m during the second 10.0 s of its motion.Homework Equations xf= xi + vi +1/2a(t)^2 x= vi + atThe Attempt at a Solution a= 4 m/s^2 x=50 mits wrong

yeah the force they produce instantly stopI rewrote the question in the way it was typed in my online assigment.

Homework Statement A rock of blasts of vertically from rest on the launch pad with an upward acceleration 2.60 m/s^2= At 30s after blast off, the engine suddenly fails, which means the force they instantly stops.Homework Equations The Attempt at a Solution How high above the launch pad will...

620 + 120 one-way = 740 620 - 120 one-way = 500 2000/740 mph = 2.70 2000/500 mph = 4 = 6.7 hoursis that correct

i did 620-120= 500 so that makes 4000/500= 8 hoursfor 1 other it only affects 1 trip so 2000/620= 3.225 2000/500= 4 so trip time = 7.225 both answers wrong
