10 pts gestion A 96-g toy car is propelled by a compressed spring that starts it moving. The car follows the curved track as shown in Figure. Find the altitude gained by the toy car if its initial speed is 3.39 m/s and it coasts up the frictionless slope and gains 0.7 m/s final speed. Equation: 5 mu? = mv + mgh where g = 9,8 m

2m 20 1m You have built an enormous spring-loaded Hot Wheels track that will propel a 50 gram toy car through a loop and launch it across the room. The spring constant is 800 N/m, the spring launcher has an initial spring displacement of 5 cm. What is the maximum radius R of the loop such that the car moves around the loop without falling off at the top, so that the toy car can make to the end point...

SECTION 3 FORMATIVE ASSESSMENT O Reviewing Main Ideas 1. If the spring of a jack-in-the-box is compressed a distance of 8.00 cm from its relaxed length and then released, what is the speed of the toy head when the spring returns to its natural length? Assume the mass of the toy head is 50.0 g, the spring constant is 80.0 N/m, and the toy head moves only in the vertical direction. Also disregard the mass of the spring. (Hint: Remember...

The spring shown in the figure is compressed 58 cm and used to launch a 100 kg physics student. The track is frictionless until it starts up the incline. The student's coefficient of kinetic friction on the 30 degree incline is 0.14. (Figure 1) Part A What is the student's speed just after losing contact with the spring? Express your answer to two significant figures and include the appropriate units. upsilon = Part B How far up the incline does...

A wooden block with mass 1.95 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 35.0degree (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.00 m up the incline from A, the block is moving up the incline at a speed of 6.15 m/s and is no longer in contact with the spring. The coefficient of kinetic between the...

A 1000 kg race car starts from rest and reaches a speed of 100 km/h in 20 s. What is the power delivered by the car’s engine? (2 points). A 1 kg mass is released from the top of a smooth slide of height 2m. At the bottom of the slide the mass slides on a horizontal surface and stops at a distance of 5 m. What is the coefficient of kinetic friction of the horizontal surface? (3.5 points). The...

A spring with spring constant k is positioned vertically and then compressed from its equilibrium length by a distance Delta y (Figure 1). A ball of mass m is placed on top of the spring, and is launched into the air when the spring is released (this setup is similar to the projectile launcher seen earlier in the semester). The ball travels to a maximum height h_max. Using the Work-Kinetic Energy theorem, determine h_max in terms of the given variables...

3m Susand a) A block with a mass of 10.0 kg is AS released from rest at the top of an 1 00.kg inclined track (0 = 30°), at point A, 3.0m above the horizontal (see the figure). The track A to B has a coefficient of kinetic friction of 0.10. The horizontal portion of the track, B to C, is 4.Om long - 4m and is frictionless. At point C, where the horizontal track ends, the block touches the...
