In this lesson, we will learn how to solve problems about the motion of a projectile on an inclined plane.
An archer shot an arrow with a speed of
at an angle of
above the horizontal.
Calculate the arrow’s horizontal range
. Also calculate its vertical height
above the launch point when it was at a distance of
46 m from the archer.
Give your answers in metres correct to one decimal place.
Consider the acceleration due to gravity to be 9.8 m/s2.
A boulder was catapulted with a speed of 14 m/s at an angle of elevation of
on horizontal ground, which is 6 m away from a castle wall that is 6 m high. Did the boulder go over the wall? Take
A catapult flung a boulder from the top of a castle wall with a speed of
at an angle
above the horizontal,
The boulder landed on the ground a distance of
66 m from the wall.
Calculate the time it took for the boulder to reach the ground and find the height of the castle wall.
