Question

A ball is dropped from a balloon going up at a speed of 10 msIf the balloon was at a hieght of 40m the maximum hieght reached by the ball respect to ballon
please answer in detail I will mark as branliest​

Answer 1

Answer:

Here is your answer

Explanation:

Given,

Speed=7m/s

height=60m

So, initially, the ball is going the upward,

u=−7m/s, s=60m ,a = g = 10m/s^2

s=ut+ 1÷2 gt ^2

60=−7t + 1÷2 10t^2

5t ^2 −7t− 60=0

t= 7±root 49 + 4 × 5 × 60÷2 x 5

t=7 ± 35.34 ÷ 10

Taking +ve sign then we get

t=7 ± 35.34 ÷10

=4.2s

Thus, the ball will take time in reaching the ground is:4.2s
