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

Problem 2: A certain spring has a spring constant k₁ = 660 N/m as the spring is stretched from x = 0 to x1 = 35 cm. The spring constant then changes to k₂ = 250 N/m as the spring is stretched to x2= 65 cm. From x₂= 65 cm to x3 = 89 cm the spring force is constant at F3 = 105 N.

A golfer hits a shot to a green that is elevated 2.50 m above the point where the ball is struck. The ball leaves the club at a speed of 19.5 m/s at an angle of 40.0° above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands. V = i

A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 3.88 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.99 m. What will the block s speed be when it reaches x = 0?     6.72 m/s     4.75 m/s     3.33 m/s     9.41 m/s

A helicopter is dellvering food in an emergency situation, where it is difficult to land. The engineer is tasked with determining what heights the package could be dropped without breaking. She knows that if the package strikes the ground faster than the critical speed of 62.0mph, then the package will break. Neglect drag At what height would the package hit the ground with the critical speed (in given units? Could the package be safely dropped from a height of 30m? yes no

A drone at too great a height drops a box. The box drops straight down the ground and hits at 100 m/s smashing the contents. Neglecting air friction, approximately, how high, in m, was the drone? O 360 O 720 O 250 O 510 O 25

A ball of mass m = 6 kg is dropped from a height (hi = 10 m) above the ground. Find the speed of the ball when it is at a height (hf = 4 m) above the ground.

(a) How long (in s) will it take an 860 kg car with a useful power output of 42.0 hp (1 hp = 746 W) to reach a speed of 17.0 m/s, neglecting friction? (Assume the car starts from rest.) 3.966 (b) How long (in s) will this acceleration take if the car also climbs a 2.60 m-high hill in the process? 14.02 X s

A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 2.58 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.51 m. What will the block s speed be when it reaches x = 0?     1.47 m/s     9.69 m/s     6.92 m/s     4.89 m/s

A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 4.49 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.64 m. What will the blocks speed be when it reaches x = 0?     3.90 m/s     2.34 m/s     7.18 m/s     5.52 m/s
