Four projecties are fired with the same velocity at angle, 25o,40o,55o and 70o with the horizontal. The range of projectile will be largest for the one projected at angle
Correct answer: B. 40o
- A. 70o
- B. 40o
- C. 55o
- D. 25o
Explanation
as R=vi 2 sin20/g all the projectiles have same speed so, R∝sin20 Range will be greater for the angle whose sin20 value will be greater For option A =Sin2(70) =0.64 For option B =Sin2(40) =0.98 For option C =Sin2(55) =0.93 For option D = Sin2(25) =0.76 As 0.98 is the greatest value so range of projectile launched at 40° will be maximum

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.

A bullet is fired horizontally from a rifle at a distant target. Ignoring the effect of air resistance, what is the horizontal and vertical acceleration of the bullet?
A projectile is projected with kinetic energy (K.E). If it has the maximum possible horizontal range, then its kinetic energy at the highest point will be:
A car travels equal distance in the same direction with velocities 60km h-1, 20km h-1 and 10km h-1 respectively. The average velocity of the car over the whole journey of motion is:
A particle is moving eastwards with a velocity 5 ms-1, in 10 s, the velocity changes to 5 ms-1 northward. The average acceleration in this time is:
