A projectile launch test is carried out with the same firing speed of 200 ft / s, the first is fired at 53o above the horizontal and the second is fired with a delay of two seconds at 90o above the horizontal.

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
