A toy shoots on the ground. If the speed is 4.5 m / s at an angle of 37 degrees, which distance is covered?

If a toy is able to draw on the ground at a speed of 4.5 m / s at an angle of 37 degrees, how far it will travel? Mass is not known. Please show your Working ...

Mass is not necessary for this issue ... This vector analysis ... For the vector V to 37 degrees is the component horizontal will be 4.5 m / s * cos37 = 4.5 m / s * 7986 = 3.59 m / s The vector will be vertical: 4.5 m / s * Sin37 = 4.5 m / s * , 6018 = 2.71 m / s Gravity will overcome this vector vertical so: v = g * t * t ^ 2 v / tg = 2.71m / s / 9.8 m / s ^ 2 = tt =, 2765 Since this is the time to reach the summit, the highest trgectory, time is exactly the same thing to fall if we multiply that time by 2 t = 5530 seconds last part horizontal distance: d = v * td = 3.59m / s *, 5530 sd = 1.99 m or 2.0 m (sigfig)
