Q22. As shown in the image below, the force acting on the 5-kg crate is a function of time. The coefficient of kinetic friction between the crate and the surface is uk = 0.15. Determine the magnitude of the horizontal impulse (in N-s) done by all external forces to the crate during the period from t = 0 to t= 2.3 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g = 9.81 m/s2. %3D F = (201² +30) N (t in second) F = F. 30 V1 Your Answer: Answer
A heavy goods vehicle of total mass 4.8 tonnes descends a hill with a gradient of 8 degrees from the horizontal. During this motion, the vehicle experiences a rolling resistance to its motion of 880 N. Whilst travelling at a velocity of 72 km/h, its brakes are applied, and the truck is brought uniformly to rest in a distance of 140 m. During this period of constant deceleration, it may be assumed that the rolling resistance remains constant at 880N, this being in addition to the retarding force applied by the brakes. Calculate for the vehicle whilst it is slowing down: a) The vertical height through which it descends. b) Its decrease in potential energy. c) Its initial velocity in m/s. Its decrease in kinetic energy.

Q13. As shown in the image below, the force acting on the 23-kg box is F = (C.s) N, where constant C = 2 and s is displacement in m. If the box has initial velocity of 1.2 m/s when s = 0, determine the power of force Fwhen s = 2.7 m. The ground is smooth. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper Sl unit. S | s Your Answer: Answer units F
Can anyone help me with this question
A block of mass m=1.64kg is released from rest at an unknown height h. The coefficient of friction between the block and the incline oriented at an angle of 0=56° is Uk=0.38. If the speed of the block v=7m/s when it leaves the inclined plane, determine the work done by the force of gravity. Take g =9.81m/s? and express your final result using one decimal place. m h т
