# Projectile motion - velocity and distance

Projectile motion -- velocity and distance

## Homework Statement

A projectile is launched with an initial speed of 60 m/s at an angle of 30 degrees above the horizontal. The projectile lands on a hillside 4 seconds later. Neglect air friction. What is the projectile's velocity at the highest point of it's trajectory? What is the straight line distance from where the projectile launched to where it hits it's target?

x=vt

## The Attempt at a Solution

For my B I got 207 m but the answer in the book says 212 m.
