a bus is moving downhill at a slope of 5 degree . at the moment when the speed of the bus is 30km/h,the driver spots a deer 30m ahead. he applies the brakes and comes to a stop. the is paralysed by fear and does not move.will the bus stops before reaching it or will it hit the deer? do relevant calculation and draw force diagram.take the coefficient of kinetic friction to be 0.26

Calculate the friction force of the skidding bus. From that and the downhill component of the weight, get the deceleration rate.

That and the initial velocity will get to the stopping distance.

Be sure to convert the 30 km/h speed to m/s before doing the calculations.

Show work for further assistance, if needed.
