If a projectile is fired with an initial velocity of vo meters per second at an angle a above the horizontal and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equations x = (vo cos(a)t y = (vo sin(a)t - +- 1012 where g is the acceleration due to gravity (9.8 m/s2). (Round your answers to the nearest whole number.) (a) If a gun is fired with a = 30°...
4. A bullet is fired vertically upward with an initial velocity of 260m/s. a) How high does it go? b) How long does it take to reach maximum height? c) How long is it the air ? ( or time to hit the ground) Farh 5. The volume of a cylinder is: Vanrh If V=2,500 m and h = 17 m find the value ofr
At a height h = 44.0 m above the ground a rocket is fired at an initial speed v0 = 168.0 m/s at an angle θ = 27 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component...
1)A bullet is fired vertically upward from a gun with an initial velocity of 235 m/s. How high does the bullet go? How long does it take to reach its maximum height? How long is it in flight? 2)Calculate the kinetic energy of a 0.350 kg baseball thrown at a velocity of 36.0 m/s.
A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.6 meters above the ground. 2.8 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.7 m/s from a height of 28.2 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. ) What is the speed of the...
You toss a racquetball directly upward and then catch it at the same height you released it 1.28 s later. Assume air resistance is negligible. (a) What is the acceleration of the ball while it is moving upward? magnitude m/s2 direction (b) What is the acceleration of the ball while it is moving downward? magnitude m/s2 direction (c) What is the acceleration of the ball while it is at its maximum height? magnitude m/s2 direction (d) What is the velocity...
If a projectile is fired with an initial velocity of v0 meters per second at an angle α above the horizontal, and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equationsx=(v0 cos α) t y=(v0 sin α) t-1/2 g t2where g is the acceleration due to gravity (9.8 m / s2)(a) If a projectile is fired with α=45° and v0=900 m / s, when will it hit the ground? How...
