Questions
The height y and the distance x along the horizontal plane of a projectile on a certain planet (with no surrounding atmosphere) are given by y = (8t - 5t2) m and x = 6t m, where t is in seconds. The velocity with which the projectile is projected at t = 0 is
detailed solution
Correct option is A
x=6t,ux=dxdt=6 y=8t-5t2,vy=dydt=8-10t vy(t=0)=8 ms-1 u=ux2+uy2=62+82=10 ms-1Talk to our academic expert!
Similar Questions
Assertion : When the velocity of projection of a body is made n times, its time of flight becomes n times.
Reason : Range of projectile does not depend on the initial velocity of a body.
