A 263 g ball of clay falls onto a vertical spring.The spring constant k = 2.52 N/cm.The clay sticks to the spring and as the spring compresses a distance of 11.8cm the clay momentarily comes to rest
How much work is being done(in J), due to gravity as the spring is being compressed
How much work is being done(in J), by the spring as the spring is being compressed
Determine the speed of the clay just before it hit the spring in m/s
Find the maximum compression of the spring, in cm, if the initial speed of the clay doubled
Find the gained potential energy in (J)
Find the average power in (W)
As the child reaches the end, his speed is 12 m/s and the distance traveled along the slide is 108 m. Find the mechanical energy, in (J), lost by the child is sliding down the slide.
During sliding his speed is 12m/s and the distance traveled along the slide is 108 m. Determine the average frictional force, in(N) acting on the boy

A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.

A sports car as rigid body needs to make a record jump from acertain ramp with some specific height covering certain horizontal distance.

A company wishes to build a science park at a coastal location in the UK.
To demonstrate its commitment to sustainability, the company wants to develop renewable method of powering the buildings.
They are considering three options:
• Biofuel
• Geothermal power
• Wind turbines
Explain the use of renewable resources to power the science park

The car needs to jump through horizontal distance of at least 20 Cars with some suitable height. The Car driver wishes to take the complete one role manoeuvre i.e. rotation along the motion of axis, into the air so that manoeuvre be completed successfully (for rigid body-based analysis condition).
