A projectile is fired from level ground with an initial speed of 24.3 m/s at a...
A projectile is fired with initial speed V_0 = 30.0 m/s from level ground at a target that is on the ground, at distance R = 20.0 m, as shown in Fig. 4-51. What are the (a) least and (b) greatest launch angles that will allow the projectile to hit the target?
An M-16 is fired from level ground at an upwards angle of 10 degrees with respect to the horizontal. The initial velocity of the bullet is 948 m/s, but because it is fired at a 10 degree angle, the vertical component of the initial velocity is 165 m/s and the horizontal component is 934 m/s. Ignore air resistance and the curvature of the earth in this problem. (Hint: See the videos Projectile Motion Parts 9-13. For questions 9-14 and 17,...
A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle of 24° with respect to the horizontal and with an initial speed of 25 m/s. Air resistance is negligible in this situation. Call up the positive y-direction, and toward the wall the positive x-direction. What is the earliest time when the height of the...
A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle 11° with respect to the horizontal and with an initial speed of 46 m/s. Air resistance is negligible in this situation. Call up the positive y direction, and toward the wall the positive x direction. What is the earliest time when the height of...
A large cannon is fired from ground level over level ground at an angle of 55 above the horizontal. This initial speed is 384 m/s. Neglecting air resistance, how far will the projectile travel in the horizontal direction before striking the ground?
A projectile is fired from ground level with an initial speed of 350 m/sec and an angle of elevation of 30 degrees. Use that the acceleration due to gravity is 9.8 m/sec^2.
6. A projectile is fired with an initial speed vo 30.0 m/s from level ground at a target that is on the ground, at distance R-20.0 m. a) (5) What is the least launch angle1 b) (51) What is the largest launch angle? 7. A particle is in uniform circular motion about the origin of an XY coordinate system, moving clockwise with a period of 10.00 sec. At one instant, its position vector is r =-201 m. At that instant,...
A projectile is launched from ground level with an initial speed of 43.5 m/s at an angle of 33.7° above the horizontal. If it strikes a target in the air 2.41 seconds later, what are the horizontal and vertical distances from where the projectile was launched to where it hits the target?
a projectile is fired with an initial speed of 2000 m/s at an angle 21 degrees above the horizontal. if air resistance is neglected , what is the velocity in m/s at the highest point of trajectory ?
A projectile is launched from ground level with an initial speed of 45.5 m/s at an angle of 32.5° above the horizontal. It strikes a target in the air 2.64 s later. What is the horizontal distance from where the projectile was launched to where it hits the target? horizontal: 59.59 What is the vertical distance from where the projectile was launched to where it hits the target? Im vertical: 74.19
