小明同学学习物理后养成了观察、思考生活的好习惯．他的质量是50千克，一次骑自行车上学，在水平路面上以4m/s的速度匀速行驶．有关数据如表所示．（g取10N/kg）

（1）小明同学骑车沿直线匀速行驶10min前进的距离是多少？

自行车净重200N
行驶时自行车与地总接触面积0.01m2
匀速行驶过程中的总阻力30N
轮胎承受的最大压强1.2×105Pa
（2）在行驶过程中，小明和车对地面的压强是多大？

答案

已知：速度v=4m/s，时间t=10min=600s，人的质量m=50kg，车重G车=200N，g=10N/kg，行驶时自行车与地总接触面积S=0.01m2

求：（1）10min前进的距离s=？；（2）小明和车对地面的压强p=？

（1）∵v=

s
t
，

∴骑自行车行驶的距离：

s=vt=4m/s×600s=2400m；

（2）人的重力G人=mg=50kg×10N/kg=500N，

自行车对地面的压力：

F=G人+G车=500N+200N=700N，

自行车对地面的压强：

p=

F
S
=
700N
0.01m2
=7×104Pa．

答：（1）10min前进的距离为2400m；

（2）小明和车对地面的压强为7×104Pa．
