A grapefruit is tossed straight up with an initial velocity of 50 ft/sec. The grapefruit is...
A bullet is shot straight in the air with an initial velocity of 139 ft/sec. Calculate how high (absolute value in ft) it will go up before it stops and reverses its motion. Assume g resistance is negligible. tion 5 1 pts A heavy object with negligible buoyancy enters water at a speed of 10 m/sec. Assuming a constant deceleration rate of -3.6 m/s2 in water, calculate how deep does it travel below the surface (absolute value of depth) before...
We throw a grapefruit straight upward into the air. Table 2.1 gives its height, y, at time t. What is the velocity of the grapefruit at exactly t 1? We use average velocities to estimate this quantity. Height of the grapefruit above the ground Table 2.1 6 0 t (sec) ys(t) (feet) 90 1422 150 30 We throw a grapefruit straight upward into the air. Table 2.1 gives its height, y, at time t. What is the velocity of the...
A rock is thrown upward at an initial velocity of 16 ft/sec from a height of 96 feet above ground. How long will it take to hit ground?
A projectile is launched straight up from ground level with an initial velocity of v0 per sec. Neglecting air resistance, its height in feet, s, after t seconds after launch is given by the equation s = –16t2 + v0t. At what time(s) will the projectile reach a height of 112 feet when v0 = 96 feet/sec? After how many seconds will it return to the ground when v0 = 96 feet/sec?
An arrow is shot straight up with an initial velocity of 50 m/s. a. Find the time to reach the highest point. b. How high does the arrow go? c. Find the arrow's height when the velocity is 25 m/s.
A ball is tossed straight upwards with an initial velocity of .30.00 metres per second from a height of 20,000 meters. Assume that the only force acting on the object is acceleration due to Earth's gravity. Write out the position and velocity functions. With what velocity does the object hit the ground? When the object hits the ground, it bounces back up with one-fourth the speed that it had when it hit the ground. Determine the height of the ball...
During practice a football player throws a football straight up into the air to see how high it will go. The initial velocity of the football was 7.6 m/s, and he released it .80 m from the ground. Find the maximum height the ball reached from the ground.
A rock is projected directly upward from ground level with an initial velocity of 90 ft per sec. The function in height of the rock in terms of time t is f (t) = −???? + ???. Find time t at which the rock reaches its maximum height and the maximum height in feet. Round answers to two decimal places, if necessary.
A 736-lb object is launched from the ground with an initial upward velocity of 60 ft/sec. The atmosphere resists the motion of the object with a force of 3 lb for each ft/sec of speed. Assuming that the only other force acting on the object is gravity, find the time it takes for the object to reach its maximum height:
Fill in the Blanks A golf ball is projected upward from ground level at an initial velocity of 112 ft/sec. The height of a projectile can be modeled by s(t) = -16t+ vot + So, where t is time in seconds, So is the initial height in feet, and Vo is the initial velocity in ft/sec. a. How high will the ball be after 2 sec? O feet b. What is the maximum height the ball reaches? O feet c....
