Find the equation of trajectory.
An axle with a diameter of 100mm has a force of 10N applied to it, what is the torque at the wheel?
Two projectiles are thrown with the same initial velocity, one at an angle and the other at an angle of . (a) Can both projectiles strike the ground at the same distance from the projection point? (b) Can both projectiles be in air for the same time interval?
A projectile is launched horizontally from the top of a vertical cliff with a velocity of 15m/s is observed to strike the ground at a distance of 45m from the foot of the cliff. What is the angle the path of the projectile makes with the ground after the moment of impact
A projectile is launched with an initial speed of 46.0 m/s at an angle of 35.0° above the horizontal. The projectile lands on a hillside 3.95 s later. Neglect air friction. (Assume that the +x-axis is to the right and the +y-axis is up along the page.)
(a) What is the projectile's velocity at the highest point of its trajectory?
