Q8. A 23-kg box was thrown onto a 34-kg cart with a speed of 9 m/s in the as shown. The cart is initially at rest. After the box lands on cart, it continues to move to the right at a speed of 2.5 m/s relative to the cart. Determine the speed of the cart. Neglect the friction between the cart and the ground. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper SI unit. V Your Answer: Answer units

The coefficient of kinetic friction between the60-kg crate and the ground is uf = 0.3.

Determine the speed of block in Q1 when it moves 2m up the slope using the Work and Energy method and calculate the power of the force P.  (If you can apply the principle of work and energy or conservation of enegry.)  Plus can you not use the required method for this question. Question 1: A 5kg block is pushed up along the slope as shown. The coefficient of kinetic friction is uk =0.2. Determine the speed of the block when it moves 2 m up the slope using Newton's Second Law. I also gave the answer for Q1 if it helps: V = 2.21m/s
