An object is shot straight upward from sea level with an initial velocity of 700 ft/sec. a. Assuming that gravity is the only force acting on the object, give an upper estimate for its velocity after 5 sec have elapsed. Use g= 32 ft/sec- for the gravitational acceleration. b.Using At = 1 sec, find a lower estimate for the height attained after 5 sec.
A 500-lb object is released from rest 500 ft above the ground and allowed to fall under the influence of gravity. Assuming that the force in pounds due to air resistance is - 25v, where v is the velocity of the object in ft/sec, determine the equation of motion of the object. When will the object hit the ground? Assume that the acceleration due to gravity is 32 ft/ sec and let x(t) represent the distance the object has fallen in t seconds. Determine the equation of motion of the object. x(t) = 3] When will the object hit the ground? The object will hit the ground after 3 seconds. (Round to three decimal places as needed.)
A Bullet with a mass of 5.2 grams is fired out of a rifle. The bullet’s initial velocity is 0 m/sec. Its muzzle velocity is 850 m/sec (in the direction the barrel is pointing). The barrel is 60 cm long. Assume that the acceleration inside the barrel is the same for the entire length of the barrel. What is the acceleration in m/sec2 and what is the time it takes for the bullet to travel down the barrel? (You must solve two simultaneous equations. vf = vi + at ; s= vit + 1/2at2) Acceleration time
