Maddie has decided to take a job as the new mascot of the MN United Loons. For her new stunt, she will stand on the lower deck and kick a ball, straight up to land in a bucket held by an assistant on the edge of the upper deck. If she kicks the ball straight up with a velocity of 24m/s and it lands in the bucket after 2.5 seconds, how high is the upper deck?

2 baskets of mass M and 2M attached to ends of massless rod length D , they are in static equilibrium, a ball is thrown into the M basket with the ball mass being 2M and the 2M basket has an M ball thrown into it calclate the angular velocity immediatly

The speed of light in a vacuum is 3.00 x 108 m/s. Calculate the speed of light in diamond (n=2.42).

An object placed 12 cm to the left of a converging lens forms an image on a screen 36 cm to the right of the lens. Calculate the focal length of the lens.

Light is travelling through air with an index of refraction of 1.00, at an angle of 30o, it then enters a mystery liquid and refracts at an angle of 14o This means that the index of refraction of the mystery liquid is:

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).
