2 Algebraic manipulation. The figure shows three spaceships engaged in a celestial tug-of-war over a rhodium-rich asteroid. F₁ F₂ 0, all three forces are coplanar, and they sum to zero so the asteroid has no acceleration. Express F3 in terms of F₁ if F2= BF₁ with 3 = 3.89. Fill in the missing numerical factor below. F3 F₂ F3 = _______________F₁ F₁ Record your answer below, assuming three significant figures.

Kindly do parts A,B and C

A car traveling at 60 km / h can brake and stop in a distance d = 20 m (figure a). If the car travels twice as fast, that is, 120 km / h, what will be the distance braking (figure b)? Assume that the maximum braking force is approximately regardless of its speed

A boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided.  Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?
