What is the maximum distance we can shoot a dart, from ground level, provided our toy dart gun gives a maximum initial velocity of 3.55 m/s and air resistance is negligible
A. 12.6 m 

B. 2.57 m  
C. 0.642 m  
D. 1.28 m 
d = v^{2} sin(2*theta)/g
it will travel the maximum distance for theta = 45 degree
> d max = v^{2} sin(2*45)/g
= (3.55^2)/9.8
= 1.285 m

What is the distance we can shoot a dart, provided our toy dart gun gives a maximum initial velocity of 2.78 m/s and is aimed at 45 degrees above the horizontal direction? A). 0.79m B). 1.58m C). 1.39m D). 2.00m
A springloaded toy gun is used to shoot a ball of mass m=1.50kg straight up in the air, as shown in (Figure 1) . The spring has spring constant k=667N/m. If the spring is compressed a distance of 23.0 cm from its equilibrium position y=0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the gun. Assume that...
9. A springloaded toy gun is used to shoot a ball of mass m2.50 kg straight up in the air, as shown below. The spring has spring constant k500 NI/m. If the spring is compressed a distance of 20.0 centimeters from its equilibrium position y0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the gun. Assume that...
Exercise 3.18: Constants A shot putter releases the shot some distance above the level ground with a velocity of 120 m/s 51.0 °above the horizontal. The shot hits the ground 2 08 s later You can ignore air resistance We were unable to transcribe this image
A shot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0 °above the horizontal. The shot hits the ground 2.08 s later. You can ignore air resistance.
A springloaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...
A particle launched at 70 degree from level ground (on earth) has a range of R = 252.13 m: (A sketch will help & neglect any air resistance} a) Determine the initial speed v_0 of the particle: b) Determine the time in flight T of the particle: c) Determine the maximum height H of the particle: d) For the same launch velocity v_0, determine the range R on Mars (g = 3.72 m/s): 9 A small ball rolls off the...
“Answer the following questions for projectile motion on level ground assuming negligible air resistance (the initial angle being neither nor ): (a) Is the acceleration ever zero? (b) When is the velocity a minimum? A Maximum? (c) Can the velocity ever be the same as the initial velocity at a time other than at t=0? (d) Can the speed ever be the same as the initial speed at a time other than at t=0?
An M16 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 913. For questions 914 and 17,...
A football is kicked from ground level with an initial velocity of 20.0 m/s at angle of 37.5° above the horizontal. How long is the football in the air before it hits the ground? Ignore air resistance.
