Question

A ball thrown with an initial velocity 70m/s at an angle of 35 degree with the horizantal find the vertical , horizantal componenents of velocity and write in unit vector form?

Answer 1

Let v represent the velocity and use the given information to write v in unit vector form:

v =70(cos(35°))i+70(sin(35°))j

Simplify the scalars, we get:

v ≈57.34i+40.15j

Since the scalars are the horizontal and vertical components of v ,

Therefore, the horizontal component is 57.34 feet per second and the vertical component is 40.15 feet per second.
