3) An oscillator consists of a block attached to a spring of k = 500 N/m on a frictionless surface. At a certain time (t) the displacement is found to be X(t) = 10 cm, the velocity is V(t) -22.6 m/sec and the acceleration A(t) = -150 m/sec^2. No initial conditions are given. %3D %3D

Question 23 Two frisky otters slide down frictionless hillsides of the same height but different slopes. The slope of the hill of otter 1 is 30°, while the slope of the hill of otter 2 is 60°. If both start from rest, which otter is moving faster when she reaches the bottom of her hill? O The otter that took the shorter time is moving faster. O Otter 2 is moving faster. O The heavier otter is moving faster, no matter which hill she used. O Otter 1 is moving faster. O Both otters have the same speed at the bottom.

The ABC part of the road in the figure is frictionless, beyond C the friction coefficient is u = 0.5. A ball with m = 2 kg is thrown from point A with a speed of 3 m / s. How many meters will the ball travel from point C until it stops? 3m/s 1.2 m a) 3.24 m b) O 2.53 m C) O 2.82 m d) 4.14 m e) 1.24 m

A 5.2 kg ball is rolling at a speed of 6.3 m/s when it encounters a ramp. How high can it roll up the ramp before coming to astop? (put your answer with 3 decimal places!) m

Can you please do all of them. Thank you so much

answer Q 5

A student releases a 3.9kg cart from the top of ramp and starts a stopwatch. The length from the front of the cart to the end of the ramp and the distance from the end of the ramp to the stopper are shown. Neglect backwards friction and drag and assume the cart does not lose speed transitioning from the ramp to the floor. What is the cart's acceleration on the ramp? unit | (magnitude) What is the cart's acceleration on the floor? 130cm unit (magnitude) How long does the cart take to reach the end of the ramp? 5° 200cm unit (timed from the release) How fast is the cart traveling as it hits the stopper? unit How long does the cart take to reach the stopper? unit (timed from the release) cannot be detern check answers challenge ne Calculator ound = 343m/s cant figures Rain to stop e here to search ACC t;320
