Only question A Only A a. Discuss the concept of centripetal force in two different situations? b. A stone is thrown upward at angle of 32 with a speed of 25 m/s from the top of a 50-m high building. (a) How long does it take the stone to reach the ground? (b) What is the speed of the stone just before it hits the ground? Suppose the position of a particle is given as a function of time by r(t) = x(t)i + y(t)], with x(t)-at + b and y(t) = ct2 + d, where a = 1 m/s, b = 1 m c 0.225 m/s, and d = 1 m. (a) Calculate the average velocity during th time interval from t = 2 s to t = 5 s. (b) Determine the velocity and the speed at t = 3 s. The vector position of a particle varies in time according to the equation r = 4.01-8.0Pg (a) Find an expression for the velocity and acceleration the particle as a function of time. (b) Calculate the particle's position and C. d. of
