A skateboarder enters a loop the loop with a radius of 3 meters. His velocity is 17m/s. What is his speed at 3 o'clock, 6 o'clock and 9 o' clock? Friction is negligible.

A tumbleweed rolls off a 120m high cliff with a speed of 23.6 m/s. What would the final velocity of the tumbleweed before striking the ground be if there were no air resistance?

A 2 kg block slides down a frictionless incline from a height of 5 m. What is its speed at the bottom of the incline? (Assume g = 9.8 m/s²)

A wagon with its passenger sits at the top of the hill. The wagon is giving a slight push and rolls 100. m down an incline (10.0° above the horizontal) to the bottom of the hill. What is the wagon’s speed when it reaches the end of the incline. Assume that the retarding force of friction is negligible. 

A block book is sitting at the top of a long ramp (124.8 cm). The ramp makes an angle of 64 degrees relative to the ground. How fast was the block moving initially if it was moving at 6.8 m/s at the bottom of the ramp? This ramp has a coefficient of friction of 0.  Round to 1 decimal.

A man on a motorcycle plans to make a jump as shown in the figure. If he leaves the ramp with a speed of 33.0 m/s and has a speed of 30.9 m/s at the top of his trajectory, determine his maximum height (h) (in m) above the end of the ramp. Ignore friction and air resistance. m

A 52 kg skier starts from rest at height H = 17 m above the end of a ski-jump ramp (see the figure). As the skier leaves the ramp, his velocity makes an angle of 0 = 25° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless. (a) What is the maximum height h of his jump above the end of the ramp? (b) If he increased his weight by putting on a 10 kg backpack, what would h be? End of H ramp (a) Number i Units (b) Number i Units >

Suppose I need to  toss an object of mass 5.2 up onto a shelf 5.94 meters above where my hands can reach. What is the minimum speed of toss necessary to do this? Your answer should be in meters per second, but don't write teh unit, just the number. You can approximate the acceleration due to gravity at the earth's surface as 10 meters per square second.

A block is given an initial velocity of 5.00 m/s up a frictionless incline of angle of 20.0°. How far up the incline does the block slide before coming to rest? Answer: 3.73 m

A man on a motorcycle plans to make a jump as shown in the figure. If he leaves the ramp with a speed of 32.0 m/s and has a speed of 29.9 m/s at the top of his trajectory, determine his maximum height (h) (in m) above the end of the ramp. Ignore friction and air resistance. ? m
