a parachutist opens his chute at time t=0, while falling vertically at a speed of 50.0 m/s. From the combined effects of gravity and air resistance, he is subject to anupward acceleration of ay= (40/T)e-t/T where T=6.8s. Find the parachutist's speed 10s after the chute is opened and the distance fallen during that period of time.
Is it possible for velocity to be constant while acceleration is not zero? Explain.
Can the velocity of an object be negative when its acceleration is positive? What about vice versa? If yes, give examples in each case
Two cars given by the king of France and queen of England (let them be named car F and car E) are straightly moving in a line. Their position functions are found to be respectively: z(t) = 14 m - (8m/s^2)t^2 and z(t) = - 50 m - (4m/s^2)t^2. At some point, these fancy and jaw-dropping cars from the said royals meet at about z' = 114 meters. From the given data, find the average velocity of car F from the time intervals t = 0 up to t'. A. - 16 m, B. 16 m, C. 32 m, or D. - 32 m.
A toy rocket is launched vertically from ground level (y=0m), at time t=0.0s. The rocket engine privides constant upward acceleration during the burn phase. At the instant the engine burnout, the rocket has risen to 64m and acquired a velocity of 60 m/s. The rocket continues to rise in thr unpowered flight, reaches maximum height, and falls back to the ground. What is the time interval during which the rocket engine provides upward acceleration?
First, you will investigate purely vertical motion. The kinematics equation for vertical motion (ignoring air resistance) is given by y(t)=y0+v0t−(1/2)gt2y(t)=y0+v0t−(1/2)gt2, where y0=0y0=0 is the initial position, v0v0v_0 is the initial speed, and ggg is the acceleration due to gravity. Drag the cannon downwards so it is at ground level, or 0 mm (which represents the initial height of the object), then fire the pumpkin straight upward (at an angle of 90∘90∘) with an initial speed of 14 m/sm/s. How long does it take for the pumpkin to hit the ground?

A person hits a trampoline while moving downward with a speed of 9 m/s and rebounds a short time later with roughly the same speed upward. If the person is in contact with the trampoline for about 1.8 s, what are the magnitude and direction of the person’s average acceleration during this time interval? (Hint: You can ignore the effects due to gravity
