A child plays with a toy car, and pushes it up a ramp. The car has a mass of m = 0.2 kg, and is given an applied force of Fa = 2.5 N, up the ramp, which has an angle of ? = 30°, and a length of 0.5 meters. The car has an initial velocity of v0 = 0.5 m/s, up the ramp.

a) What is the magnitude of the normal force?

b) What is the speed of the car at the top of the ramp?

c)  The moment the car reaches the top of the ramp, the child lets go, and the car is launched from it. If you ignore air resistance, how far does the car land from the ramp

1. A cylindrical wooden log rolls without slipping down a small ramp. The log has a radius of 16 cm, a length of 2.5 m, and a mass of 130 kg. The log starts from rest near the top of the ramp. When the log reaches the bottom of the ramp, it is rolling at a linear speed of 2.3 m/s. a.) Assuming that the log is a perfect cylinder of uniform density, find the log’s moment of inertia (about...

A woman attempts to push a box of books that has mass m up a ramp inclined at an angle α above the horizontal. The coefficients of friction between the ramp and the box are μs and μk. The force F⃗  applied by the woman is horizontal. Assume that μs is less than this critical value. What magnitude of force must the woman apply to keep the box moving up the ramp at constant speed?​

A 1.55-kg block is launched by a spring and slides along a ramp as shown. The spring has a spring constant of 1180 N/m and is compressed a distance, x, before being released. The block slides up a frictionless ramp of height, H=0.550 m, above where the block leaves the spring. At the top of the ramp it flies horizontally off the ramp. Just before leaving the ramp, the kinetic energy of the block is 8.54 J. After leaving the...

You are playing with some toy cars. You set up a little race car that has a mass of 120 grams to move at a velocity of 9.0 m/s due South, and a big toy truck with a mass of 350 grams at a velocity of 2.0 m/s due East. The two toys collide and stick together. What is the total kinetic energy of the toys after the collision?

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...

A child is bouncing an a trampoline. The child has a mass of 50.5 kg . She leaves the surface of the trampoline with an initial upwards velocity of 10.2 m/s . When she reaches height 1.60 m above the trampoline (still on the way up), she grabs a large (stationary) plastic block. The mass of the block is 8.00 kg . (Figure 1) For this problem, use g=9.80 meters per second per second for the magnitude of the acceleration...
