A frictionless car on a straight track tipped at 8.21° accelerates at 1.40 m/s².
Released from rest and travels through 2 photo gates. First is 18.8cm away from starting position. Second is 14.8 cm from the first one. Whats the velocity as the car passes through each gate?
I'm not sure here. The angle throws me off since the professor hasn't gone over an equation with an angle involved yet.
The Attempt at a Solution
I just could use the formula that would be used. I tried using Vf² = Vi² + 2aΔx ... but then realized the angle wasn't taken into account
