Question 3 (a) A 60 kg block is at rest on a smooth horizontal surface as shown in Fig. 23a. A force of 90 N acting at an angle of 35° is applied to the block for 7s. Determine the final velocity and the normal force which the smooth surface exerts on the block during the time interval F-90N u=0 Fig. 23a (5 marks) (b) A ball of mass 625 g hits the ground with the following velocity...

The professor didn't make an answer key for this study guide and I wanted to know if I'm doing these right. 4. A man pushes with a force of 700 N on a broken down car at an angle of 0 degrees from horizontal. He manages to move it form to a garage. How much energy does he use? 5. A block sits on a horizontal surface with friction. The mass of the block is kg. A force of 14Nis...

1. Jane always loved skateboarding, but with all of her new free time she decides to learn how to rail slide. But her father tells her to start small, so she goes to the top of her family's van (which is 2.5 m high) and skates off of it with a speed of 13 m/s. How far from the base of the van will she land? 2.Loic and Miriam meet at a park to play social distancing football. Where they...

Q3
QUESTION 3 The block with mass of 10 kg is attached with the spring located on the smooth plane as shown in Figure Q3. The plane has been raised to 8 =30° from horizontal surface. When the force F= 200 N is applied, the block started moving down the plane with a speed of 2 m/s. We know that when s = 0.4 m, the spring in an unstretched condition. Given the spring has a stiffness, k=300 N/m (a)...

(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
