Chapter 2, Problem 2.56P

CALC A lunar lander is descending toward the moon’s surface. Until the lander reaches the surface, its height above the surface of the moon is given by y(t) = bct + dt2, where b = 800 m is the initial height of the lander above the surface, c = 60.0 m/s, and d = 1.05 m/s2. (a) What is the initial velocity of the lander, at t = 0? (b) What is the velocity of the lander just before it reaches the lunar surface?

​Suppose the position vector for a particle is given as a function of time by , with x(t) = at + b and y(t) =ct2 + d, where a = 1.00 m/s, b = 1.00 m, c= 0.125 m/s2, and d = 1.00 m. (a) Calculate the average velocity during the time interval from t = 1.00 s to t = 4.00 s. (b) Determine the velocity and the speed at t = 3.00 s. (c) Determine the acceleration at t = 3.00 s.
A projectile is launched with a launch angle of 30° with respect to the horizontal direction and with an initial speed of 26 m/s.    How do the vertical and horizontal components of the projectile's velocity vary with time?The initial velocity in the x-direction vx0 is related to the initial speed by vx0 = v0 cos 30°. The constant velocity in the x-direction means that the equation describing the time dependence of x for the particle, with x0 taken as 0, is x = x0 + vx0t = 0 +       m/s    t. The equation for the vertical coordinate, which is constantly accelerating downward at g = 9.8 m/s2, is y = y0 + vy0t −  1 2 gt2 =      m/s    t +      m/s2    t2.
Suppose the position vector for a particle is given as a function of time by  r(t) = x(t)î + y(t)ĵ, with x(t) = at + b and  y(t)=ct2 + d, where a = 1.70 m/s, b = 1.20 m, c = 0.133 m/s2, and d = 1.12 m. (a) Calculate the average velocity during the time interval from t = 2.05 s to t = 3.80 s. v =         m/s (b) Determine the velocity at t = 2.05 s. v =       m/s (c) Determine the speed at t = 2.05 s. m/s
