A rocket blasts off from rest and attains a speed of 59.4 m/s in 14.1 s. An astronaut has a mass of 66.7 kg. What is the astronaut's apparent weight during takeoff?
I figured this out.. So basically you find the acceleration first V-Vo/t= 59.4-0/14.1 = 4.21m/s2
then, you find the apparent weight by multiplying 66.7*(9.8 + 4.21)= 934.47N
