1.5- Dynamics

Question 1

How can you calculate the horizontal distance travelled

Answer 1

Horizontal velocity X time of flight

Question 2

State the 4 equations of motion

Answer 2

V= U+at
S= 1/2(u+v)t
S=ut + 1/2at^2
V^2=U^2 + 2as

Question 3

When is the range at its maximum value?

Answer 3

When the angle of projection is at 45
The range when projected at an angle is the same as for a particle projected at an angle (90-angle)

Therefore a particle projected at 30 degrees has the same range as one projected at 60 degrees
