A bus of mass 2500kg goes round a corner of radius 50m at a speed of 5m/s. what force is needed for the bus to go round the corner?
m v^2/r
2500 (25)/50
= 1250 Newtons
I dont get what i need 👎
To calculate the force needed for the bus to go around the corner, you can use the concept of centripetal force. Centripetal force is the force required to keep an object moving in a curved path. The formula for centripetal force is F = (mv^2)/r, where F is the centripetal force, m is the mass of the object, v is the velocity, and r is the radius of the curve.
In this case, the mass of the bus is given as 2500 kg, the velocity is 5 m/s, and the radius of the curve is 50 m. Plugging these values into the formula, we get:
F = (2500 kg) * (5 m/s)^2 / 50 m
Simplifying the equation, we have:
F = (2500 kg) * (25 m^2/s^2) / 50 m
F = 31250 kg m^2/s^2 / 50 m
F = 625 N
Therefore, the force needed for the bus to go around the corner is 625 Newtons.
