Q17. As shown in the image below, the 0.5-kg ball strikes the rough ground and rebounds. The directions of its velocities before and after the strike are shown. If the speeds are vị = 21 m/s and v2 = 13 m/s, determine the magnitude of the impulse (in N-s) the ground exerts on the ball. Assume that the ball does not slip when it strikes the ground, and neglect the size of the ball and the impulse produced by the weight of the ball. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.

Q17. As shown in the image below, the 0.7-kg ball strikes the rough ground and rebounds. The directions of its velocities before and after the strike are shown. If the speeds are v₁ = 27 m/s and v₂ = 12 m/s, determine the magnitude of the impulse (in N.s) the ground exerts on the ball. Assume that the ball does not slip when it strikes the ground, and neglect the size of the ball and the impulse produced by the weight of the ball. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. V₁ Your Answer: 45° Answer 30° 02
The 5.27 kg collar B rests on the frictionless arm AA! The collar is held in place by the rope attached to drum D and rotates about O in a horizontal plane. The linear velocity of the collar B is increasing according to v = 0.2 t2 where v is in m/s and tis in seconds. Find the tension in the rope and the force of the bar on .the collar if 5 s,r= 0.558 m and 0 = 58° A A' D
This kayaker starts at rest (v=0) and paddles for 3 seconds. The force of the paddle on the water is parallel to the kayak motion and averages 200 N for the one second that it is in the water. The paddle blade then leaves the water and both paddle blades are airborne for 0.5 second. The other blade then enters the water to begins its 1 second, 200 N power stroke followed by 0.5 second with both paddles airborne. The mass of kayaker and kayak together is 100 kg. The water exerts a constant horizontal force backward on the kayak of 100 N, regardless of speed. Ignore the force of the air (i.e. wind). All accelerations are in the horizontal direction. a) What is the average acceleration of the person+kayak when a paddle is in the water? b) What is the average acceleration of the person+kayak when both paddles are airborne? c) Plot the position, velocity, and acceleration vs. time for these 3 seconds. (Each plot must have correct calculated values at 0.0, 1.0, 1.5, 2.5, and 3 seconds). d)…
A constant force of ''F'' acts on a mass as shown. The mass starts its motion from rest at position 1, the unstretched length of the spring is 250 mm, and the spring modulus is k=1,5 k?/m. Neglecting the friction, determine the required force ''F'' to cause the 2−kg mass to have a speed of v2=1,5 m/s at position 2.
