Projectile Motion Practice
10 problems · instant feedback · full explanations
Split every projectile into horizontal (constant velocity) and vertical (constant acceleration) parts. The two motions share only the time of flight.
Q1.
On flat ground with no air resistance, which launch angle gives the maximum horizontal range?
Multiple choice · Easy
Q2.
A ball is kicked at 20 m/s at 30° above the horizontal. What is its horizontal range? (Use g = 9.8 m/s².)
Numerical answer (m) · Medium
Q3.
A rocket is launched straight up at 25 m/s. What maximum height does it reach? (Use g = 9.8 m/s².)
Numerical answer (m) · Medium
Q4.
Which pair of launch angles gives the SAME range for the same launch speed?
Multiple choice · Medium
Q5.
A javelin leaves at 18 m/s at 40° above the horizontal. How long is it in the air? (Use g = 9.8 m/s².)
Numerical answer (s) · Hard
Q6.
Ignoring air resistance, what is the horizontal acceleration of a projectile?
Multiple choice · Easy
Q7.
The horizontal and vertical motions of a projectile are independent of each other.
True / False · Medium
Q8.
A projectile launched at 60° travels farther than one launched at 30° with the same speed.
True / False · Hard
Q9.
A cannonball is fired at 30 m/s at 45°. What is its maximum height? (Use g = 9.8 m/s².)
Numerical answer (m) · Medium
Q10.
