Motion with gravity Consider the following descriptions of the vertical motion of an object subject only to the acceleration due to gravity. Begin with the acceleration equation a(t) = v′ (t) = –g, where g = 9.8 m/s2.
a. Find the velocity of the object for all relevant times.
b. Find the position of the object for all relevant times.
c. Find the time when the object reaches its highest point. What is the height?
d. Find the time when the object strikes the ground.
110. A payload is dropped at an elevation of 400 m from a hot-air balloon that is descending at a rate of 10 m/s.

- A Ferris wheel at a theme park rotates in an anticlockwise direction at a constant rate. People enter the cars of the Ferris wheel from a platform which is above ground level. The Ferris wheel does not stop at any time. The Ferris wheel has 16 cars, spaced evenly around the circular structure. A spider attached itself to the point P on the side of car C when the point P was at its lowest point at time 1.00 pm. The height, h metres, of the point P above ground level, at time t hours after 1.00 pm is given by h(t)=62+60 sin(((5t-1)pi)/2) a) Write down the maximum height, in metres, of the point P above ground level. b)Write down the minimum height, in metres, of the point P above ground level. c) At what time, after 1.00 pm, does point P first return to its lowest point? d)Find the time, after 1.00 pm, when P first reaches a height of 92 metres above ground level. e)Find the number of minutes during one rotation that P is at least 92 metres above ground level.arrow_forwardvn] An equation of the motion of the form s = 80t – 16r? represents an object thrown upward with initial velocity of 80 ft/sec. a.

- Practical Question: An object is moving horizontally with the speed of 50 m/s. When the object at the height of 2 km, an object free fall from the aircraft. Determine the type of the motion and explain A. Free fall motion B. Floating motion C. Horizontal motion D. Projectile motionarrow_forward(5) A force T is applied at the tip of the rod as shown. If the n- component of the force is T, = 35 lb, determine the t-, x-, and y-components of the force T. The t-axis is directed along the rod, and the n-axis is perpendicular to the rod. Ans: T₁ =-130.6 lb, Tx=-103.6 lb, Ty = -86.9 lb T n 40° O 55°arrow_forward3arrow_forward
