After a projectile is fired into the air, what is the magnitude of the acceleration in the y-direction? (Assume no air resistance.)A.9.8 m/s2B.19.6 m/s2C.0 m/s2D.4.9 m/s2

When a projectile is fired at an angle, what is the acceleration in the horizontal direction?Select one:a.Depends on the angle of projectionb.Equal to the initial velocityc.9.8 m/s²d.0 m/s²

In one experimental trial, the projectile was uniformly accelerated from rest to a distance of 2 m in 0.1 s.  What was the acceleration of the projectile?A.20 m/s2B.40 m/s2C.200 m/s2D.400 m/s2

A projectile returns to its original height 4.08 s after being launched, during which time it travels 76.2 m horizontally.If air resistance can be neglected, what was the projectile's initial speed?Express your answer in m/s.

The bullet fired from a gun on the ground has a velocity v. The x-component of the velocity is 7.2 ms-1 and the y-component of the velocity is 9 ms-1. x is the horizontal axis and y is the vertial axis. What is the distance in m between the gun and the point where the bullet hits the ground? Acceleration due to gravity is 9.8ms-2. Assuming there is no air resistance during the bullet's flight.

A projectile is launched from the edge of a cliff with a velocity of 15.0 m/s at an angle of 30.0 degrees above the horizontal. Ignoring air resistance, what is the velocity of the projectile 2.00 seconds later?
