Physics Questions!
Gloria is pulling her baby in his sled. The baby and sled have a mass of 75 kg. If she is holding the rope to the sled at a 45o angle and she wants to accelerate at 0.5 m/s2 how much force does she need to exert?
d = v x t vavg = ½ (vf + vi) vf = at + vi
a = (vf - vi) / t d = vi t+ ½ at 2 vf2 = vi2 + 2ad
d = (vf2 - vi2)/2a F = ma g = acceleration due to gravity = -10 m/s2; Pressure = N/m2 = Pa
