If a projectile is thrown with 19.6m/s velocity at 30o with x-axis, time taken to reach highest point?
Correct answer: A. 1 sec
- A. 1 sec
- B. 3 sec
- C. 2 sec
- D. 4 sec
Explanation
C is the correct answer. v=u+at (at max height v =0) 0=19.6 + (-10)t t=1.96s= 2s

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
