...when he comes to the top o? a) A 100 kg physics teacher is riding his 8 kg mountain bike at 5 m/s when he comes to the top of a 50 m long hill and coasts to the bottom. If the hill is a 10 degree incline, calculate his speed at the bottom of the hill.
b) At the bottom the path levels off but he hits a sandpit and tries to coact to the far side. If the coefficient of friction is 0.7, how fare into the sandpit will he go before coasting to a stop?
Please Help. Thanks.
