Question

a ball is thrown from a field with the 12m/s at an angle of 45° with the horizontal at what distance will it hit the field again.

Answer 1

is it 14.5 m .....,,, I think .

Answer 2

Answer:

According to the Question

It is given that ball is thrown from the roof with a speed of of 15m/s at an angle of 45° with the horizontal .

we need to calculate the distance will it hit the field again.

As we know that acceleration due to gravity is 10m/s².

Using horizontal range formula

• Let the distance will it hit the field be d metres .
• horizontal range = u²sin2∅/g

Substitute the value we get

➻ horizontal range = 15²Sin(2×45)/10

➻ horizontal range = 225×Sin90°/10

➻ horizontal range = 225×1/10

➻ horizontal range = 225/10

➻ horizontal range = 22.5m

Hence, the ball hits the roof again 22.5 metres from the point of projection .
