A storm broke a tree and the treetop rested 20 m from the base of the tree, making an angle of `60^@` with the horizontal. Find the height of the tree.

A boy is at a distance of 60 m from a tree, makes an angle of elevation of 60^@ with the top of the tree. What is the height of the tree?

A tree breaks due to storm and the broken part bends so that the top of the tree touches the ground making an angle of 30^@ with the ground. The distance between the foot of the tree to the point where the top touches the ground is 10m. Find the height of the tree.

A tree breaks due to storm and the broken part bends, so that the top of the tree touches the ground making an angle of 60^(@) with the ground . The distance from the foot of the tree to the point where the top touches the ground is 5 metres . Find the height of the tree. ( sqrt(3) = 1.73 )

A bomb is fired from a cannon with a velocity of 1000 m/s making an angle of 30^@ with the horizontal. What is the time taken by the bomb to reach the highest point?

An observer at a distance of 10 m from a tree looks at the top of the tree , the angle of elevation is 60^(@) . What is the height of the tree ? ( sqrt(3) = 1 .73 )

A tree is broken by the wind. The top of that tree struck the ground at an angle of 30^(@) and at a distance of 30 m from the root. Find the height of the whole tree. ( sqrt(3) = 1.73)

A person standing on the bank of a river observes that the angle of elevation of the top of a tree standing on the opposite bank is 60^(@) . When he moves 40 m away from the bank, he finds the angle of elevation to be 30^(@) . Find the height of the tree and the width of the river. (sqrt3=1.73)

A kite is flying at a height of 60 m above the ground. The string attached to the kite is tied at the ground. It makes an angle of 60^@ with the ground. Assuming that string is strainght, find the length of the string. ( sqrt3 = 1.73)

A body slides down in a time ‘f from rest along a smooth inclined plane making an angle of 45° with the horizontal. When the same body slides down from rest along a rough inclined plane of same length making the same angle, it takes time ‘pt then the coefficient of friction between the body and the rough plane is (p is a constant)
