A child and sled with a combined mass of 52.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 3.70 m/s at the bottom, what is the height of the hill? A child and sled with a combined mass of 2.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 3.70 m/s at the bottom, what is the height of the hill? m
A child and sled with a combined mass of 59.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.00 m/s at the bottom, what is the height of the hill?
A child and sled with a combined mass of 49.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.40 m/s at the bottom, what is the height of the hill? m
Starting from rest, a 30.6 kg child rides a 7.75 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.0 m/s . If the slope makes an angle of 13.3° with respect to the horizontal, how far along the hill did she slide on her sled? Child on a sled sliding down a slope from right to left. distance= __________
Starting from rest, a 28.6 kg child rides a 8.75 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 7.2 m/s . If the slope makes an angle of 14.5° with respect to the horizontal, how far along the hill did she slide on her sled?
Starting from rest, a 29.2 kg child rides frictionless ski slope. At the bottom of the hill, her speed is 8.25 kg sled down a a 6.8 m/s. If the slope makes an angle of 15.5° with respect to the horizontal, how far along the hill did she slide on C her sled? 0.235 distance Momentum and Energy 2 Based on the previous question you can conclude that if two objects of different mass have the same magnitude of momentum,...
#7 Achild and sled with a combined mass of50 kg sliding down a hill from rest would 14pts. have the speed of 3.0 m/s at the bottom, if there was no friction. a) What is the height of the hill? If the actual speed at the bottom is 2.5 m/s how much work is done by frction? #8 A 7.00 g lead bullet at 25°C traveling at 250. ms is stopped by a tree. Assuming that 65% 14pts. of the...
A block of mass 0.9 kg starts from rest and slides down a curved frictionless slide. Determine the change in the block's height when its speed has reached 4.1 m/s.
A 45 kg child slides down a straight frictionless water slide. The slide is 16 m long and set at angle of 28o above horizontal.1.Find the work done by gravity on the child.2.If the child started at rest at the top, what is the speed of the child at the bottom of the slide?
A 40-kg child slides down a curved slide starting at the top with an initial speed of 4 m/s. (a) Suppose that the slide is frictionless. Determine the speed of the child when she is 3 m below her starting height. (b) Suppose that the slide has friction. Determine the speed of the child when she is 5 m below her starting height if she starts from rest and 300 J of thermal energy is dissipated during the motion.
