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

maximum Range= V^2/g
=3.55^2/9.8
=1.28 m
Ans:D d = v2 sin(2*theta)/g

it will travel the maximum distance for theta = 45 degree

--> d max = v2 sin(2*45)/g

= (3.55^2)/9.8

= 1.285 m

A spring-loaded 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...

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,...
