Gary, an online physics student, has a mass of 80.5 kg. his new bicycle has a mass of 13.7 kg. gary is pedaling so that a net (unbalanced) force of 9.86 n accelerates him and his bicycle. what is the value of the acceleration?
notice the two masses are added together because the 9.86 n force accelerates the system of masses.
m = 13.7 kg + 80.5 kg = 94.2 kg
f = 9.86 n
a = ?
f = ma
a = f/m = 9.86 n/94.2 kg
f = 0.10467 m/s2
f = 0.105 m/s2

Which of these statements is true? a. quarks pair with leptons to form protons and neutrons. b. quarks pair with bosons to form photons. c. quarks pair with photons to form protons and neutrons. d. quarks pair with other quarks to form protons and neutrons. e. quarks pair with electrons to form protons.

Which of the following is not a means to accelerating? question 4 options: a)increase speed b)remain still c)decrease speed d)change direction

Amerry-go-round of radius r, shown in the figure, is rotating at constant angular speed. the friction in its bearings is so small that it can be ignored. a sandbag of mass m is dropped onto the merry-go-round, at a position designated by r. the sandbag does not slip or roll upon contact with the merry-go-round. how would you rank the following different combinations of m and r on the basis of the angular speed of the merry-go-round after the sandbag "sticks" to the merry-go-round from largest to smallest. a) m = 10kg, r = 0.25r b) m = 20kg, r = 0.25r c) m = 10kg, r = 0.50r d) m = 10kg, r = 1.0r e) m = 15kg, r = 0.75r f) m = 40kg, r = 0.25r
