2 Your friend is planning to ride his bike up a ramp and land on the roof of a building as shown below. The building is 6.00 m high and 8.00 m away from the ramp. The ramp is 3.00 m wide and 4.00 m tall. 4.00 m 1 ← 3.00 m 6.00 m 8.00 m A. What is the minimum speed with which your friend needs to leave the ramp in order to land on the building? B. Another friend is going to use his motorized scooter for the same stunt. The maximum speed of the scooter is 15.0 m/s. How close to the building should you move the ramp so that your friend lands on the roof right at the front edge of the building?
A 100-kg box is towed to move horizontally from rest by a constant force P=200 N. The kinetic friction is μk =0.1. The angle of the force P is θ=30° with respect to the horizontal direction. The acceleration due to gravity is g=9.81 m/s2. (5) Calculate the magnitude of the the friction force F= ___(N) (two decimal places).

QUESTION 4 A car is moving along a straight horizontal road with speed vms-¹. The magnitude of the resistance to motion of the car is given by the formula (150+ 3v) N. The car's engine is working at 10kW. Calculate the maximum value of v. O 47.9 O 17.9 O 27.9 O 37.9
A helicopter with a mass of 10,000 kg takes off straight up at t=0. The thrust of the engine is defined given as a function of time: FT= 95 0.18t- (kN). Where t is in units of seconds. How fast is it rising and what is its elevation at t=4s?
What will be the acceleration (include direction) of this system of blocks connected by rope and pulley"! Mass x = 2.82 kg and mass y = 1.10 kg. Assume that the rightward direction is positive. Ignore any friction in the table or pulley or any elasticity of the rope. 0.59 kg x kg D y kg Round your final answer to the nearest thousandth. Use g-9.81 m/s^2. Include metric units. As always please use "A" for power, as in "ft^2" for square feet.
F = (C · t²) Q14. As shown in the image below, the force acting on the box is N, where constant C = 10 and t is time in s. Determine the magnitude of the total impulse (in N.s) done by force F to the box during the period from t = 0 to t = 1.5 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. F Your Answer: Answer 3 5 4
