initial velocities

The velocity-time graph passes through the origin and is inclined to the time-axis such that the angle of inclination is greater than 0 o and less than 90 o , as shown in the figure...

An object is hurled upward from the ground with an initial velocity of 73.5 m/s. After what time will the object reach a height of 245 m? => 6s, 11s or 6s, 10s or 5s, 10s or 5s, 11s..

Write the equation which is used to model the height of an object that is thrown down with an initial velocity of - 8 feet per second from a height of 18 feet. => h = - 16 t 2 + 8 t + 18 or h = - 16 t 2 + 18 or h = - 16 t 2 - 8 t + 18 or h = - 16 t 2 - 8 t - 18..

Jeff throws a pen from the top of a 124 feet tall building with an initial downward velocity of - 30 feet per second. How long will the pen take to reach the ground? => 2 or 30 or 124 or - 3.785..

John hits a ball when it is 3 ft above the ground . The ball leaves the bat with an initial velocity 20 ft/sec, at 60° angle with the horizontal and heads towards a 9 ft wall at a distance of 8 ft . At what height does the ball hit the wall? => 9 ft or 8 ft or 6.6 ft or 8.6 ..

All bodies when projected vertically upwards fall back to earth due to the earth's gravitational pull. The maximum height attained by a body depends upon the initial velocity of the bod..

All bodies when projected vertically upwards fall back to earth due to the earth's gravitational pull. The maximum height attained by a body depends upon the initial velocity of the body. This does not mean that no object can escape earth's gravitational pull. We know that the s..

Jim can jump with an initial velocity of 4 feet per second. To catch the ball hit by a baseball hitter, he has to jump 11 feet. The equation for the height of his jump is h = -16 t 2 + 4 t + 4. Using the discriminant, find whether he can catch the ball. => No or Yes..

Jake can jump with an initial velocity of 5 feet per second. To catch the ball hit by a baseball hitter, he has to jump 5 feet. The equation for the height of his jump is h = - 16 t 2 + 5 t . Use the discriminant to find whether he can catch the ball. => No or Yes..

Integrating the above equation and applying the limits which are at s = 0, initial velocity = u after a distance s has been covered, the final velocity = ..
