Most of the information's required for solving the question is already given in the question. Height of the building that casts a shadow of 20 m = 32 m Then Height of the man that casts a shadow of 1.2 m = (32/20) * 1.2 meter = 3.2 * 1.2 meter = 3.84 meter So the actual height of the person casting a shadow of 1.2 meter is 3.84 meters. I hope that the procedure used for solving the problem is easy enough for you to understand. You can definitely use this method in future for solving problems of similar type without requiring any additional help from outside.
A child's toy consists of a piece of plastic attached to a spring in the figure below. The spring is compressed against the floor a distance of 2.00 cm, and the toy is released. If the toy has a mass of 117 g and rises to a maximum height of 45.0 cm, estimate the force constant of the spring.
