a race car is approaching a jump ramp with the ramp angle at 10 degrees and 20 meters long and is 3.47 meters off the ground, the car will leave the ramp and enter free fall, the landing ramp is 15 meters away and is 1 meter off the ground, what is the minimum velocity the car can go to make the jump?
Three equal point charges, each with charge 1.30 mu C, are placed at the vertices of an equilateral triangle whose sides are of length 0.600 m. Evaluate the electric potential energy U of the system?
The string connecting the m1 and the m2 passes over a light frictionless pulley. Given m1 = 1.77 kg, m2 = 7.24 kg, m3=2.23 kg, and g = 9.8 m/s2. The acceleration of gravity is 9.8 m/s2 . Find the downward acceleration of m2 mass.
An electric vehicle starts from rest and accelerates at a rate of 1.6 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle after that slows at a constant rate of 1.4 m/s2 until it stops. (1) How much time elapses from start to s..
