Question

pls give correct ans

Answer 1

Answer:

Given

u = 10i + 4j

x-component of u = 10m/s

y-component of u = 4m/s

final velocity vector = v (at maximum height)

x-component of v = 10m/s

y-component of v = 0

acceleration =10m/s^2

acceleration =(velocity)^2/radius

10=10x10/R

Radius = 10m
